Crash when exiting a map view

[ynibling]

Platforms

Android

Version of flutter-maplibre

0.3.3+2

Bug Description

I have a list of different routes. When I click on one of them, I create a new widget containing Maplibre and display the route based on a GeoJson.

With go_router (16.3.0), I have a return route to go back to the list of routes. When I click on the return button, the application crashes.

I am using Android Studio to emulate an Android phone.
I tried with an without the filter option and the application crashes in both cases.
I tried with maplibre 0.3.2 and the back button works fine without crashing.

Steps to Reproduce

1. Create a list with ListenableBuilder widget
2. Add a route to each item
3. Click on one of them
4. Display a route and a back button
5. Click on the back button

Expected Results

After clicking the back button, the list of routes is displayed again.

Actual Results

The application crashes with this error:

Code Sample

The widget I use to contain maplibre

Interesting, who could have guessed that 0.3.2 is quite stable - well it has other problems I guess.😄
It will take a couple of days until find the time to take a look at it. My first instinct suggests that this bug might have been introduced in #434. You can try to revert this commit and check if that solves the problem if you want.

I tried what you suggested and it seems to be working. I can't reproduce the crash!

[josxha]

I added additional guards to the map disposal logic in #481. I wasn't able to reproduce this issue yet. Could you check please if the bug persists when the 0.3.4 release comes out?

Hello,

Unfortunately, after updating Maplibre to version 0.3.4 I was unable to compile my project. I got the following error:

I forced cronet client to version 1.7.0, I got the same error

The example app compiles fine in the ci. Can you try flutter clean?
