颤振错误：参数类型“未来”<Image> &#39; 不能分配给参数类型 &#39;Widget&#39;

Question

i'm using flutter flame library and got this error

The argument type 'Future<Image>' can't be assigned to the parameter type 'Widget'.

my code is:

import 'package:flutter/material.dart';
import 'package:flame/flame.dart';

class TileMap extends StatefulWidget {
  @override
  _TileMapState createState() => _TileMapState();
}

class _TileMapState extends State<TileMap> {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Flame.images.load('grass_05.png'),
    );
  }
}

how to fix it? and what's the problem? thank's to all

Answer 1

class _TileMapState extends State<TileMap> {
  @override
  void initState() {
    super.initState();
    _loadImage()
  }

  void _loadImage() async {
    var img = await Flame.images.load('grass_05.png');
    setState(() => _image = img);
  }

  Image _image;

  @override
  Widget build(BuildContext context) {
    return Container(
      child: _image,
    );
  }
}
