這只是其中2種簡單的方法，后續(xù)會補充，請持續(xù)關(guān)注

這是完整dome代碼，直接復(fù)制放入main.dart就可以了

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

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    debugPaintSizeEnabled = true;
    return MaterialApp(
        home: Scaffold(
      appBar: AppBar(
        title: Text("image實例dome"),
      ),
      body: Center(
        child: Column(
          children: [
            //加載網(wǎng)絡(luò)圖片
            Image.network(
              "https://b1.sbimg.org/file/chevereto-jia/2020/12/14/Qct2l.png",
              width: 300,
            ),
            //加載asset圖片
            // Image.asset("assets/image/..png"),
            MemoryImageWidget()
          ],
        ),
      ),
    ));
  }
}

class MemoryImageWidget extends StatefulWidget {
  @override
  _MemoryImageWidgetState createState() => _MemoryImageWidgetState();
}

class _MemoryImageWidgetState extends State<MemoryImageWidget> {
  @override
  Widget build(BuildContext context) {
    return Container(
      child: Text("這是什么"),
    );
  }
}
