在flutter中配置local_auth插件 [英] configure local_auth plugin in flutter

问题描述

我的项目，使用kotlin，当我想使用Local_auth插件时，出现以下错误：

My project , uses kotlin and when I want to use Local_auth plugin , I get the error below:

PlatformException(no_fragment_activity, local_auth plugin requires activity to be a FragmentActivity., null)

local_auth的示例说的是：

what the example of local_auth says , is:

package io.flutter.plugins.localauthexample;

import io.flutter.embedding.android.FlutterFragmentActivity;
import io.flutter.embedding.engine.FlutterEngine;
import io.flutter.plugins.localauth.LocalAuthPlugin;

public class MainActivity extends FlutterFragmentActivity {
  // TODO(bparrishMines): Remove this once v2 of GeneratedPluginRegistrant rolls to stable. https://github.com/flutter/flutter/issues/42694
  @Override
  public void configureFlutterEngine(FlutterEngine flutterEngine) {
    flutterEngine.getPlugins().add(new LocalAuthPlugin());
  }
}

和

package io.flutter.plugins.localauthexample;

import android.os.Bundle;
import io.flutter.app.FlutterFragmentActivity;
import io.flutter.plugins.GeneratedPluginRegistrant;

public class EmbeddingV1Activity extends FlutterFragmentActivity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    GeneratedPluginRegistrant.registerWith(this);
  }
}

但问题是我不知道Kotlin而且我不知道如何创建我的kotlin文件。

but the problem is that I don't know kotlin and I don't know how to create my kotlin file.

另外，我猜（我不确定），这可能是新版中出现抖动的错误

also , I guess (I am not sure) that , it can be a bug of flutter in its new release.

推荐答案

将 MainActivity.kt 文件的代码更改为此

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

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