突然，Flutter 应用程序在打开时开始崩溃。早些时候它正在工作。分享运行时崩溃日志 -

Fatal Exception: java.lang.IncompatibleClassChangeError: Found interface com.google.android.gms.location.SettingsClient, but class was expected (declaration of 'com.google.android.gms.location.SettingsClient' appears in /data/app/com.test.app-AqARftTPn1XJdiHWXXbkBw==/base.apk!classes6.dex)

由于我已将 flutter SDK 升级到 1.12.13+hotfix.8，片段中较旧的 FlutterView 实现不再起作用，因为 Facade (Flutter) 库现在已弃用。

Flutter.createView(activity!!, lifecycle, mRoute)

根据官方文档，我们可以添加如下所示的 FlutterFragment -

FlutterFragment flutterFragment = FlutterFragment.withNewEngine()
    .initialRoute("myInitialRoute/")
    .build();

但是找不到如何在扩展 Flutter 片段的自定义 Flutter 片段中添加方法通道。
