[deeplink] Path of my flutter project is not recognized

[sbatezat]

I'm trying to debug deep links as per this documentation https://docs.google.com/document/d/1fnWe8EpZleMtSmP0rFm2iulqS3-gA86z8u9IsnXjJak

It's asked to enter the path of the local project, but it seems my project cannot be well scanned. I'm always having the error dialog "You selected a non Flutter project".

My path looks like this
/Users/USERNAME/dev/MyApp

What's wrong?

---

DevTools version: 2.31.1
IDE: VSCode
Connected Device:
CPU / OS: arm64 (64 bit) android
Connected app type: Flutter native (debug build)
Dart Version: 3.3.4
Flutter Version: 3.19.6 / stable
Framework / Engine: 54e66469a9 / c4cd48e186

I've just upgraded my Flutter SDK from 3.19.6 to 3.22.0 and so my DevTools is now 2.34.3.
The problem is still there (my project path appears on the new combo box, but when I click on the "validate deep links" button, a popup still claims this is not a Flutter project)

Hi @sbatezat , to help me understand the bug better

1. Are you using the devtool in a browser or in vscode/android studio? If you have a screenshot , it will be helpful.
2. Are other functions in the devtool working properly for this app? For example, inspector, memory

Hi @Hangyujin

1. The information is on the issue, I'm using VSCode. However, I've tested it on a Chrome browser and the result is the same.
2. Others functions are working properly

I can't see how screenshot can help, but here it is :-)

@sbatezat are you using windows? there is currently a bug that looks similar to what you are seeing.

@CoderDake No, I'm not targetting Windows and I'm working on macOS

i'm also getting this issue, any updates?

[hannah-hyj]

#7767 @chunhtai just merged a PR to show more error messages if the path is not recognized. It will help this issue.
It can happen due to many reasons, maybe the devtool server is not running, maybe the analyze command failed.

Can you run the command "flutter analyze --android --list-build-variants" in terminal under your project path (for example: "/Users/USERNAME/dev/MyApp") to see if it can successfully get build variants?

BUILD FAILED in 9s

I understand why the command is failing. I'm using --dart-define-from-file "env/. development.env" to run/debug my app, and this is adding dynamically an application id on the app.
Without that option, there is no application id, and your command is failing.

Here is how it's implemented on build.gradle

def dartEnvironmentVariables = [];
if (project.hasProperty('dart-defines')) {
    dartEnvironmentVariables = project.property('dart-defines')
        .split(',')
        .collectEntries { entry ->
            def pair = new String(entry.decodeBase64(), 'UTF-8').split('=')
            [(pair.first()): pair.last()]
        }
}

android {
    defaultConfig {
        applicationId dartEnvironmentVariables.ANDROID_APPLICATION_ID
    }
}

Here is the VSCode configuration to take this into account from the IDE

{
            "name": "Android - DEV",
            "request": "launch",
            "type": "dart",
            "program": "lib/main.dart",
            "toolArgs": [
                "--dart-define-from-file", "env/.development.env"
            ]
},

How can I solve that issue?

Hi @sbatezat

Can you try to create an example project with the setup you describe? that way it will be easier for us to try to figure out how to support your use case

Tested with the sample counter app, and one a bit more complicated with GoRouter and Shell routes. Both projects not recognised as flutter apps. One was just generated by the cli.

Using the deep links test tool inside vs code and in browser
The issue I have identified is related to the paths to flutter apps in the dropdown.

When the path is typed correctly in the field the deep link checker works
