**App Version**: This refers to the version that the application will be set to. Setting a version number is optional, but may be required for specified cases.
23+
**Build Number**: The build number is used for deployment. Each time it is successfully deployed this should increase by 1 until a new version is set (at which point it will be reset to 1)
24+
If left empty, it will automatically increment the build number each time it is deployed. ​​**After incrementing the app version and build number from the previous one, you can deploy it once more.**​​**2. Deploying From GitHub **
25+
Step 1: Open the `pubspec.yaml` file.
26+
Step 2: Locate the **`version`** tag.
27+
Step 3: Update the build name and number such as `version: ^1.0.2+2`.NB: Use the latest Flutter `version `package

# Adding dependencies in pubspec.yaml file for entire Project
11+
12+
FlutterFlow does not support adding dependencies to the entire project yet, but here is the workaround, you can add dependencies in your Custom widgets or Custom Actions which will be added in the pubspec.yaml file.​
13+
To add dependencies in your Custom widgets or Custom Actions you can follow the steps mentioned below:
14+
15+
Step 1: Add the dependencies
16+
17+
Step 2: Click on the Refresh icon to update the dependencies
18+
19+
Step 3: Import it inside the code

# Advanced Push Notification Troubleshooting
11+
12+
If push notifications are not sending as expected, this article will help you identify and correct the most common issues.
13+
14+
**Please note that push notifications will not work in these situations:**
15+
16+
Push notifications will not work on an iOS simulator. To test you will need to use a real device. Here are instructions on how to do this.
17+
18+
Push notifications will not work if the user is not logged in to your app.
19+
20+
Push notifications will not work if you have the app open on your device.
21+
22+
**Ensure you have created a push notification key for Apple.**
23+
Apple requires developers to create a key for the push notifications inside the Apple Developer Console to verify the push notification's sender.
24+
25+
Head to your Apple Developer account and select Certificates, Identifiers & Profiles > Keys.
26+
27+
![](../assets/20250430121405271522.png)If you haven't added a push notification key, you will need to add this.
28+
29+
Here are instructions on how to add a push notification key.​
30+
**Ensure you have added the APN key to Firebase.**
31+
Head to the Firebase Console and open the project dashboard for your project (click the project tile). Select Project Settings > Project Settings > Cloud Messaging.
32+
33+
Scroll down to the iOS section. If you have no files listed under APNs Authentication Key (like the photo below), you need to upload the APN Key.
34+
35+
![](../assets/20250430121405587477.png)Here are the instructions on how to upload the APN key to Firebase.​
36+
**Ensure you have added a push notification identifier for Apple.**
37+
You must add an Identifier to be able to send the push notifications to the iOS devices after you deploy your app to the app store.
38+
39+
Head to your Apple Developer account and select Certificates, Identifiers & Profiles.
40+
41+
![](../assets/20250430121405921022.png)If you haven't created a push notification identifier, you will need to add this.
42+
43+
Here are instructions on how to create your push notification identifier.
44+
45+
**Ensure you are using the latest version of FlutterFlow**
46+
To upgrade to the latest version of FlutterFlow select Ctrl + R on Windows or Cmd + R on Mac.
47+
48+
After you have done this, clear your browser cache and log out/in to FlutterFlow.

# App Store Deploy Button Not Working
2+
3+
---
4+
5+
**Problem:**
6+
When attempting to deploy your application to the App Store, the deploy button may become unresponsive. If you inspect the browser's console, you might see the following error:
7+
8+
```text
9+
POST https://api.flutterflow.io/v1/codemagicBuildRequest 503
10+
```
11+
12+
---
13+
14+
## Why Does This Happen?
15+
This error typically occurs when your project contains very large assets (such as videos or large images). If the total project size exceeds the recommended limit, the deployment request is rejected by Codemagic.
16+
17+
- **Recommended project size:** 50 MB or less
18+
19+
---
20+
21+
## How to Fix
22+
1. **Remove Large Assets:**
23+
- Identify and remove large files (especially videos or high-resolution images) from your project assets.
24+
- Instead, host these files externally (e.g., on a CDN or cloud storage) and access them via network URLs.
25+
2. **Check Project Size:**
26+
- Ensure your project remains under the 50 MB limit.
27+
28+
---
29+
30+
## Still Not Working?
31+
If you have reduced your project size and the issue persists, please contact FlutterFlow support via [Chat](https://flutterflow.io/support) or email: [[email protected]](mailto:[email protected]).

# Backend query don't return any results even though I have data in my database
11+
12+
Issue
13+
You have data in your Firestore database, but your backend query is not returning any results.
14+
There are a number of issues that may cause this issue. Here are some of the most common issues to check for:​
15+
You've not deployed the correct rules for that particular collection that is not returning the data
16+
In some cases, when you create a new collection in the project, the user forgets to setup and deploy the rules for that collection. Please take a look at the firebase section and deploy the correct rules​
17+
![](../assets/20250430121237764753.png)
18+
You've enabled the Ignore Empty Filter Values Option and have missing or Null Data
19+
In the example below, we have a filter on created_time and have enabled the Ignore Empty Filter Values Option. This means the query will ignore all the documents that:
20+
21+
Don't have the created_time field
22+
23+
Have the created_time field, but it is null
24+
25+
![](../assets/20250430121238081846.png)To troubleshoot this:
26+
27+
Check to see if your query has the Ignore Empty Filter Value Option enabled
28+
29+
Review your database or CMS to make sure that your documents have the field you are using on your filters.
30+
31+
**You have Ordering on your query and the field you selected as order doesn't exist or is null**
32+
If you use a field for order, and that is null or does not exist in the document, FlutterFlow will ignore that document and not load it.
33+
34+
In the example below, signinDate is set to be order by Increasing.
35+
36+
If my list returns no documents, this means none of my documents doesn't have the signinDate field or it is null
37+
38+
If my list only returns 99/100 documents, this means that one document doesn't have the signinDate or it is null
39+
40+
![](../assets/20250430121238384085.png)
41+
**In case of APIs returning empty results**
42+
If the APIs are working fine in test mode but do not return any data in the deployed app, mostly it is due to the CORS issue, please take a look at the browser's console to see if it shows any errors regarding CORS (check the screenshot for reference). If yes, please take a look at this article to understand and resolve the problem.​
43+
![](../assets/20250430121238656194.png)**The issue was not resolved.**
44+
45+
If the error still persists after following the outlined steps, please contact support via Chat or Email at [email protected].

# Build Failed: Error loading project for test or run mode.
11+
12+
Issue
13+
You receive this error when you try to create a new build in Run or Test mode, but you don't have any identified issues in your FlutterFlow project.​
14+
![](../assets/20250430121245553425.png)**What does this error mean?**
15+
There is an issue in your FlutterFlow project that is stopping your code from compiling.
16+
17+
We typically try to notify you of potential project issues using the debug menu (example below). However, sometimes there are new error types that our system does not catch.

Flutterflow Bug, It may be a bug and you need to report it in our github issue tracker if you find it.
30+
31+
Troubleshooting This Error Type
32+
33+
If you have the ability to download your code, run the code in your local machine. You can check the last code and see the error in the code. With this information, you can return to the FlutterFlow editor and fix the issue.
34+
35+
You can also review your previous snapshots to identify the changes made that caused the error. For example, if the last thing you did was duplicate the page bookings and change some of it.Go to that page, check all the actions, Visibility rules, and open them one by one to find a red noticed item there.**Example of how an error could be hidden:**
36+
37+
![](../assets/20250430121246143405.png)Here in this visibility rule, you can't see any error. but let's see after opening the condition what we could see
38+
39+
![](../assets/20250430121246510364.png)
40+
You could see after opening the second value, we could see it's unset and red. Simply it could cause a build failure when we run the project.​
41+

# Can I Import Modified Source Code Back into FlutterFlow?
11+
12+
Currently, FlutterFlow does **not** support importing source code that has been manually edited in an IDE (such as Android Studio or VS Code) back into the FlutterFlow platform.
13+
14+
> **Note:**
15+
> You can still run your modified source code from GitHub in Test Mode, but you cannot sync those changes back into the FlutterFlow visual builder.
16+
17+
---
18+
19+
If you need to make custom code changes, it's recommended to maintain those changes outside of FlutterFlow and manage your workflow accordingly.

# Can't Download APK or Code in FlutterFlow
11+
12+
**Check Your Browser Permissions**
13+
The most common cause of issues downloading APKs or project code is insufficient permissions in your web browser. To download your code, you'll need to give FlutterFlow permission for pop-ups and redirects.
14+
15+
For Chrome, please follow these steps:
16+
17+
Select the **lock icon** in the website address bar.
18+
19+
A popup will appear. Ensure it says **Allow **next to pop-ups and redirects.
20+
21+
Additionally, we recommend you **Allow Clipboard **as well. You need this to copy-paste widgets within FlutterFlow.
22+
23+
Once done, try downloading the APK again.
24+
25+
***Tip: The download will be saved in your default download folder. ***​​
26+
![](../assets/20250430121527145863.png)
27+
28+
**Resolve Project Errors**
29+
30+
You won't be able to download your APK or code if your project has errors. If you see a red indicator (example below) in your project issues, this means you have unresolved errors you need to address. It should also show an error mentioning to fix the errors before building the APK.​
31+
After resolving all the issues, you should be able to download the APK
32+
33+
![](../assets/20250430121527462964.png)
34+
By following these steps, you can troubleshoot and resolve common issues you may encounter while downloading the code. If you still face challenges, don't hesitate to reach out to our support team by emailing [email protected]/

# Can't deploy Firestore Database rules
11+
12+
This article will walk you through troubleshooting steps if you are unable to deploy your Firebase Rules.
13+
14+
**1. Validate that you have created your Firestore Database**
15+
Without a database created in the Firebase project, there is no way for FlutterFlow to deploy your rules. ​
16+
Open the Firebase Console for your project and select Create database.
17+
18+
Video:
19+
Create a firebase firestore database in Firebase to start [ time: 1:50 to 2:05 ]
20+
21+
![](../assets/20250430121312243075.png)
22+
**2. Validate that the three necessary permissions are granted**
23+
24+
In order to deploy Firebase Rules, you will need to add the following cloud permissions for [email protected]: Editor, Cloud Functions Admin, and Service Account.
25+
26+
Head to the Firebase Console and open the project dashboard for your project (click the project tile). Select Project Settings > Users & Permissions.
27+
28+
If you don't have Cloud Functions Admin, Editor, and Service Account listed next to [email protected], you have not completed this step.
29+
30+
Here is a video you can watch to see how you can add the permission
31+
32+

Validate that you have selected the GCP location for your Firebase project**Head to the Firebase Console and open the project dashboard for your project (click the project tile). Select Project Settings > General.
33+
34+
If you see **Not yet selected,** you have not completed this step.
35+
36+
![](../assets/20250430121313453827.png)Select the pencil and complete setup.
37+
38+
Tip: Once created, this can not be changed. You can learn more about selecting locations here.​
39+
**After checking these 3 steps, you should be able to successfully deploy your database rules. **
