1. Primeiro criei uma classe que alterasse a cor do container dependendo do nivel e da dificuldade da tarefa

import 'package:flutter/material.dart';

class ColorContainner extends StatelessWidget {
  final int level;
  final int difficulty;

  const ColorContainner(this.level, this.difficulty, {super.key});

  Color typeColor (int level, int difficulty){
    if ((level/difficulty) < 10){
      return  Colors.blue;
    } else if ((level/difficulty) <20){
      return Colors.green;
    } else if ((level/difficulty) <30){
      return  Colors.amber;
    } else if ((level/difficulty) <40){
      return  Colors.brown;
    } else if ((level/difficulty) <=50){
      return Colors.red;
    } else {
      return Colors.black;
    }
  }

  @override
  Widget build(BuildContext context) {
    return Container(
      decoration: BoxDecoration(
              borderRadius: BorderRadius.circular(10.5),
              color: typeColor(level, difficulty),
            ),
            height: 140,
    );
  }
}

1. Importei para o meu arquivo Task a classe ContainnerColor como primeiro filho da minha arvore de widget da minha Stack.

import 'package:flutter/material.dart';
import 'package:to_do_list/components/container.dart';
import 'package:to_do_list/components/difficulty.dart';

class Task extends StatefulWidget {
  final String name;
  final String photo;
  final int difficulty;

  const Task(this.name, this.photo, this.difficulty, {super.key});

  @override
  State<Task> createState() => _TaskState();
}

class _TaskState extends State<Task> {
  int nivel = 0;
  void levelUp() {
    setState(() {
      nivel++;
    });
  }

  @override
  Widget build(BuildContext context) {
    return Padding(
      padding: const EdgeInsets.all(8.0),
      child: Stack(
        children: [
          ColorContainner(nivel, widget.difficulty),
          Column(
            mainAxisAlignment: MainAxisAlignment.spaceBetween,
            children: [
              Container(
                height: 100,
                decoration: BoxDecoration(
                  borderRadius: BorderRadius.circular(2),
                  color: Colors.white,
                ),
                .
                .
                .
                  ),
                 Padding(
                    padding: const EdgeInsets.all(10.0),
                    child: Text(
                      (nivel/widget.difficulty) <= 50 ?
                      'Nivel: $nivel' :
                      'Nivel Mestre',
                      style: const TextStyle(
                        color: Colors.white,
                        fontSize: 16,
