创建插件VideoViewPlugin实现FlutterPlugin：
package io.flutter.plugins.videoplayer;import android.util.Log;import androidx.annotation.NonNull;import io.flutter.embedding.engine.plugins.FlutterPlugin;import io.flutter.embedding.engine.plugins.activity.ActivityAware;import io.flutter.embedding.engine.plugins.activity.ActivityPluginBinding;public class VideoViewPlugin implements FlutterPlugin, ActivityAware { private final static String TAG = "VideoViewPlugin"; FlutterPluginBinding fpBinding; @Override public void onAttachedToEngine(@NonNull FlutterPluginBinding binding) { fpBinding = binding; Log.e(TAG, "onAttachedToEngine"); } @Override public void onDetachedFromEngine(@NonNull FlutterPluginBinding binding) { Log.e(TAG, "onDetachedFromEngine"); } @Override public void onAttachedToActivity(@NonNull ActivityPluginBinding apBinding) { fpBinding.getPlatformViewRegistry().registerViewFactory("plugins.my_video_player/view", new VideoViewFactory(fpBinding, apBinding)); Log.e(TAG, "onAttachedToActivity"); } @Override public void onDetachedFromActivityForConfigChanges() { Log.e(TAG, "onDetachedFromActivityForConfigChanges"); } @Override public void onReattachedToActivityForConfigChanges(@NonNull ActivityPluginBinding binding) { Log.e(TAG, "onReattachedToActivityForConfigChanges"); } @Override public void onDetachedFromActivity() { Log.e(TAG, "onDetachedFromActivity"); }}由于引用视频播放器时需要用到Activity的context，所以实现了ActivityAware接口，在onAttachedToActivity方法中注册PlatformViewFactory！
创建VideoViewFactory实现PlatformViewFactory：
package io.flutter.plugins.videoplayer;import android.content.Context;import io.flutter.Log;import io.flutter.embedding.engine.plugins.FlutterPlugin;import io.flutter.embedding.engine.plugins.activity.ActivityPluginBinding;import io.flutter.plugin.common.StandardMessageCodec;import io.flutter.plugin.platform.PlatformView;import io.flutter.plugin.platform.PlatformViewFactory;public class VideoViewFactory extends PlatformViewFactory { private final static String TAG = "VideoViewFactory"; private final FlutterPlugin.FlutterPluginBinding fpBinding; private final ActivityPluginBinding apBinding; public VideoViewFactory(FlutterPlugin.FlutterPluginBinding fpBinding, ActivityPluginBinding apBinding) { super(StandardMessageCodec.INSTANCE); Log.e(TAG, "VideoViewFactory"); this.fpBinding = fpBinding; this.apBinding = apBinding; } @Override public PlatformView create(Context context, int viewId, Object args) { Log.e(TAG, "PlatformView-create:" + args.toString()); return new VideoViewPlayer(args.toString(), fpBinding, apBinding); }}创建VideoViewPlayer，实现PlatformView和MethodChannel.MethodCallHandler：
package io.flutter.plugins.videoplayer;import android.app.Activity;import android.content.Context;import android.util.Log;import android.view.LayoutInflater;import android.view.View;import androidx.annotation.NonNull;import androidx.annotation.Nullable;import com.th.kjjl_flutter.R;import com.videoplayer.player.VideoView;import io.flutter.embedding.engine.plugins.FlutterPlugin;import io.flutter.embedding.engine.plugins.activity.ActivityPluginBinding;import io.flutter.plugin.common.MethodCall;import io.flutter.plugin.common.MethodChannel;import io.flutter.plugin.platform.PlatformView;public class VideoViewPlayer implements PlatformView, MethodChannel.MethodCallHandler { private final static String TAG = "VideoPlayerView"; Activity context; private VideoView videoView; private MethodChannel methodChannel; VideoViewPlayer(String viewId, FlutterPlugin.FlutterPluginBinding fpBinding, ActivityPluginBinding apBinding) { this.context = apBinding.getActivity(); videoView = (VideoView) LayoutInflater.from(context).inflate(R.layout.video_player, null); methodChannel = new MethodChannel(fpBinding.getBinaryMessenger(), "my_video_player_" + viewId); methodChannel.setMethodCallHandler(this); } @Override public void onMethodCall(@NonNull MethodCall call, @NonNull MethodChannel.Result result) { Log.e(TAG, "call.method>>" + call.method); switch (call.method) { case "setUrl": String url = call.arguments.toString(); videoView.initVideoController(context); videoView.setUrl(url); break; case "start": videoView.start(); break; case "pause": videoView.pause(); break; case "release": videoView.pause(); videoView.release(); break; case "stopFullScreen": videoView.stopFullScreen(); break; default: result.notImplemented(); } } @Nullable @Override public View getView() { return videoView; } @Override public void dispose() { Log.e(TAG, "dispose>>"); videoView.pause(); videoView.release(); methodChannel.setMethodCallHandler(null); methodChannel = null; }}其中的VideoView即引用的第三方播放器库，你可以根据自己情况，使用常见的安卓端开源播放器如GSY，饺子，DKPlayer等！
video_player.xml：
<?xml version="1.0" encoding="utf-8"?><com.videoplayer.player.VideoView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/videoView" android:layout_width="match_parent" android:layout_height="match_parent" />在MainActivity中注册插件：
class MainActivity : FlutterActivity() { override fun onCreate(savedInstanceState: Bundle?) { super.onCreate(savedInstanceState) flutterEngine!!.plugins.add(VideoViewPlugin()) }}注意：不要在GeneratedPluginRegistrant中去注册插件包括IOS，这个类由系统自动生成其它第三方插件注册代码！安卓端在MainActivity中注册，IOS端在AppDelegate中注册！
