Why is HasCollidables mixin not being recognized in FlameGame?-CodePudding

In my programm the HasCollidables Mixin is not beeing recognized. When I hover over "HasCollidables" it says "Classes can only mix in mixins and classes. (dartmixin_of_non_class)". I have the up to date Flutter Version (3.3.10) my Flame Version is 1.5.0.

import 'package:flame/geometry.dart';
import 'package:flutter/material.dart';
import 'package:flame/game.dart';
import 'package:flame/components.dart';

void main() {
  var game = MyGame();
  runApp(
    GameWidget(
      game: game,
    ),
  );
}

class MyGame extends FlameGame with HasCollidables {
  Future<void> onl oad() async {
    print('loading assets');
  }

Is something wrong with the code? I saw the exact code running on other machines.

I tried out adding and removing imports to fix the problem and also to update flutter and flame to the newest version, but that didn't help so far.

CodePudding user response：

HasCollidables is deprecated now. You probably want to use HasCollisionDetection mixin. Read the docs here: https://docs.flame-engine.org/1.5.0/flame/collision_detection.html
