1、在pubspec.yaml中添加image_picker:
pubspec.yaml image_picker: ^0.6.7+112、用ImageFile显示本地图片:
import 'package:flutter/material.dart'; import 'package:image_picker/image_picker.dart'; import 'dart:io'; void main() => runApp(MyApp()); //ImageFile本地资源图片,和AssetImage不同,前者是显示手机中存储的图片,而后者是显示app内的图片,需要在pubspec.yaml中设置图片路径 class MyApp extends StatefulWidget { MyApp({Key key}) : super(key: key); @override _MyAppState createState() => _MyAppState(); } class _MyAppState extends State<MyApp> { //File属于IO库 File _image; //获取图片 Future getImage() async { var image = await ImagePicker.pickImage(source: ImageSource.gallery); setState(() { _image = image; }); } @override Widget build(BuildContext context) { return MaterialApp( title: 'ImageFile本地资源图片', home: Scaffold( appBar: AppBar( title: Text('ImageFile本地资源图片'), ), body: Center( child: Column( children: [ Center( child: _image == null ? Text('您还未选择任何图片') : Image.file( _image, scale: .5, fit: BoxFit.cover, ), ), FlatButton( onPressed: getImage, child: Text('选择图片'), ) ], ), ), ), ); } }
