flame-1.9.1/lib/src/game/flame_game.dart:279:30: Error: Member not found: 'hidden'.

[kavi6024]

This is the first time I am working with the Flame framework, and following the tutorial provided on Bare Flame game, I have this code.

`import 'package:flame/game.dart'; import 'package:flutter/widgets.dart';

void main() { final game = FlameGame(); runApp(GameWidget(game: game)); }`

Current bug behavior

This is the behaviour of the program when I run it. (M2101K7BI is my physical device's name)

`Launching lib\main.dart on M2101K7BI in debug mode... Running Gradle task 'assembleDebug'... ../../../../AppData/Local/Pub/Cache/hosted/pub.dev/flame-1.9.1/lib/src/game/flame_game.dart:279:30: Error: Member not found: 'hidden'. case AppLifecycleState.hidden: ^^^^^^ Target kernel_snapshot failed: Exception

Steps to reproduce

This error occurred the first time I ran the program, so I don't exactly know the procedure to reproduce the same.

It seems we haven't updated the Flutter constraints of Flame but since the latest Flame version we dont support Flutter 3.10 anymore because Flutter introduced a breaking change: https://docs.flutter.dev/release/breaking-changes/add-applifecyclestate-hidden

[kavi6024]

Any way to change the AppLifecycleState enum, or to implement it maunally ? Or, is there any update coming up on Flame ?

Can't you just update your Flutter version? In the next release we'll update the constraints.
