缺少插件异常

Question

对于google\u字体和shared\u首选项的未处理插件异常，我收到一个错误：

未处理的异常：MissingPluginException（在channel plugins.flatter.io/shared_首选项上找不到方法getAll的实现）未处理的异常：MissingPluginException（在channel plugins.flatter.io/path_provider上找不到方法getApplicationSupportDirectory的实现）MethodChannel。invokeMethod（包：flatter/src/services/platform\u channel.dart:332:12）localPath（包：google\u font/src/file\u io\u desktop\u and\u mobile.dart:28:27）
googleFontsTextStyle（包：google\u fonts/src/google\u fonts\u base.dart:107:3）

Answer 1

我解决了改变代码从mainactivity.kt或mainactivity.java.

import androidx.annotation.NonNull
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.plugins.GeneratedPluginRegistrant

class MainActivity: FlutterFragmentActivity() {
   override fun configureFlutterEngine(@NonNull flutterEngine: 
     FlutterEngine) {
     GeneratedPluginRegistrant.registerWith(flutterEngine)
   }
}

之后，拍干净然后跑

Answer 2

import androidx.annotation.NonNull
import io.flutter.embedding.engine.FlutterEngine
import io.flutter.embedding.android.FlutterFragmentActivity
import io.flutter.plugins.GeneratedPluginRegistrant

class MainActivity: FlutterActivity() {
    override fun configureFlutterEngine(@NonNull flutterEngine: FlutterEngine) {
        GeneratedPluginRegistrant.registerWith(flutterEngine);
    }
}
