flutter上传区分视频和图片

在Flutter中，您可以使用`image_picker`插件来上传图片和视频。该插件允许用户从相机或图库中选择文件，并返回一个`File`对象。 要区分上传的是图片还是视频，您可以检查文件的扩展名。以下是一个简单的示例代码： ``` import 'dart:io'; import 'package:flutter/material.dart'; import 'package:image_picker/image_picker.dart'; void main() => runApp(MyApp()); class MyApp extends StatelessWidget { @override Widget build(BuildContext context) { return MaterialApp( title: 'Upload Demo', home: UploadDemo(), ); } } class UploadDemo extends StatefulWidget { @override _UploadDemoState createState() => _UploadDemoState(); } class _UploadDemoState extends State { File _file; Future _pickImage(ImageSource source) async { final pickedFile = await ImagePicker().getImage(source: source); setState(() { _file = File(pickedFile.path); }); if (_file != null) { if (_file.path.endsWith('.jpg') || _file.path.endsWith('.jpeg') || _file.path.endsWith('.png')) { // Upload image print('Uploading image...'); } else if (_file.path
