【问题标题】：Uninstalling applications in Flutter在 Flutter 中卸载应用程序

【问题描述】：

在我们的应用程序中，我们正在卸载一些第三方应用程序并使用app_uninstallerflutter(2.5.3) 插件来执行此操作。根据crashlytics，这个插件的崩溃事件数量最多，影响了 486 个崩溃事件中的 206 个用户（昨天的数据）。有没有其他方法可以卸载应用程序？应用卸载代码：

var isUninstalled = await AppUninstaller.Uninstall("com.package_name");

这是我们得到的例外：

【解决方案1】：

我所做的是完全删除卸载程序插件并使用MethodChannel调用原生android端。

在本机方面，我正在使用 Intent 卸载应用程序。请检查以下代码以供参考：

Flutter Side：

const platform = MethodChannel('com.flutter.uninstall');
String package = 'com.package.name';

var uninstallResult = await platform.invokeMethod("Uninstall", {
  "package": package,
});

原生 Android 端：

private val CHANNEL_UNINSTALL = "com.flutter.uninstall"


MethodChannel(flutterEngine.dartExecutor, CHANNEL_UNINSTALL).setMethodCallHandler { call, result ->
  if (call.method == "Uninstall") {
    val packageName = call.argument<String>("package")
    Log.e("Package Name", "$packageName")

    val intent = Intent(Intent.ACTION_UNINSTALL_PACKAGE)
    intent.data = Uri.parse("package:$packageName")
    intent.putExtra(Intent.EXTRA_RETURN_RESULT, true)
    result.success("uninstall_started")
  }
}
