Flutter Version Manager (FVM): Flutter的版本管理终极指南

import 'package:fvm/fvm.dart';
 
// 安装特定版本的Flutter
Future<void> installFlutterVersion(String version) async {
  final FlutterVersion flutterVersion = FlutterVersion(version: version);
  await flutterVersion.install();
  print('Flutter版本$version安装成功！');
}
 
// 切换到特定版本的Flutter
Future<void> useFlutterVersion(String version) async {
  final FlutterVersion flutterVersion = FlutterVersion(version: version);
  await flutterVersion.useVersion();
  print('已切换到Flutter版本$version。');
}
 
// 列出所有已安装的Flutter版本
Future<void> listInstalledFlutterVersions() async {
  final List<FlutterVersion> installedVersions = await FlutterVersion.listInstalled();
  installedVersions.forEach((version) => print(version.version));
}
 
// 删除特定版本的Flutter
Future<void> removeFlutterVersion(String version) async {
  final FlutterVersion flutterVersion = FlutterVersion(version: version);
  await flutterVersion.remove();
  print('Flutter版本$version已删除。');
}
 
// 示例使用
void main() async {
  // 安装Flutter 2.0.0版本
  await installFlutterVersion('2.0.0');
 
  // 切换到Flutter 2.0.0版本
  await useFlutterVersion('2.0.0');
 
  // 列出所有已安装的Flutter版本
  await listInstalledFlutterVersions();
 
  // 删除Flutter 2.0.0版本
  await removeFlutterVersion('2.0.0');
}

这段代码展示了如何使用FVM包来管理Flutter版本。它包含安装、切换、列出和删除Flutter版本的基本操作。通过这个示例，开发者可以学习如何有效地管理他们的Flutter项目所需的Flutter SDK版本。
