Current bug behaviour

OpacityEffect is not working on TextComponent

Expected behaviour

It should work as expected when used with component that has mixin HasPaint

Steps to reproduce

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

class OpacityEffectGame extends FlameGame {
SpriteComponent sprite;

@OverRide
Future onLoad() async {
await super.onLoad();
final textConfig =
TextPaint(config: TextPaintConfig(color: Colors.white, fontSize: 35));
final newStageComponent = TextEffectComponent('Stage',
config: textConfig, position: Vector2(size.x/2, size.y / 2))
..anchor = Anchor.center;
await newStageComponent.add(
OpacityEffect(
opacity: 0,
duration: 0.5,
isInfinite: true,
isAlternating: true,
));
await add(newStageComponent);

}

}

class TextEffectComponent extends TextComponent with HasPaint {
TextEffectComponent(String text,{Vector2 position,TextRenderer config}) : super(text, position: position, textRenderer: config);
}
