fl_pip

基于原生ios和android的画中画模式，实现显示flutter的view,可以通过修改flutter 栈顶的view来显示任意UI

The picture-in-picture mode is implemented in native ios and android to display flutter's view

目前在ios上遇到了一个问题，当app在后台的时候，FlutterUi停止运行或者画中画直接黑屏，猜测可能是由于ios冻结app导致，本人目前没有好的解决办法，如果你有想法，请提交pr

At present, there is a problem in ios, when the app is in the background, FlutterUi will stop running or black screen directly, which may be caused by ios freezing the app, I have no good solution at present, if you have ideas, please submit PR

Use configuration

• ios 配置 : Signing & Capabilities -> Capability 添加 BackgroundModes 勾选 Audio,AirPlay,And Picture in Picture
• ios configuration : Signing & Capabilities -> Capability Add BackgroundModes check Audio,AirPlay,And Picture in Picture
• 修改/ios/Runner/AppDelegate.swift 的内容
• Modify the content of /ios/Runner/AppDelegate.swift

swift

import fl_pip
import Flutter
import UIKit

@main
@objc class AppDelegate: FlFlutterAppDelegate {
    override func application(
        _ application: UIApplication,
        didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
    ) -> Bool {
        GeneratedPluginRegistrant.register(with: self)
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }

    override func registerPlugin(_ registry: FlutterPluginRegistry) {
        GeneratedPluginRegistrant.register(with: registry)
    }
}

• android 配置 : android/app/src/main/${your package name}/MainActivity 修改 MainActivity 继承,
• android configuration : android/app/src/main/${your package name}/MainActivity,

kotlin

class MainActivity : FlPiPActivity()

java

class MainActivity extends FlPiPActivity {

}

android AndroidManifest file android/app/src/main/AndroidManifest.xml, add android:supportsPictureInPicture="true"

<application android:label="FlPiP">
    <activity android:name=".MainActivity" android:launchMode="singleTop" android:supportsPictureInPicture="true" />
</application>

Methods available

/// 开启画中画
/// Open picture-in-picture
void enable() {
  FlPiP().enable(
      iosConfig: FlPiPiOSConfig(),
      androidConfig: FlPiPAndroidConfig(
          aspectRatio: const Rational.maxLandscape()));
}

/// 是否支持画中画
/// Whether to support picture in picture
void isAvailable() {
  FlPiP().isAvailable;
}

/// 画中画状态
/// Picture-in-picture window state
void isActive() {
  FlPiP().isActive;
}

/// 切换前后台
/// Toggle front and back
/// ios仅支持切换后台
/// ios supports background switching only
void toggle() {
  FlPiP().toggle();
}

/// 退出画中画
/// Quit painting in picture
void disable() {
  FlPiP().disable();
}

• 如果使用enableWithEngine方法必须在main文件中添加这个main方法
• The main method must be added to the main file if the enableWithEngine method is used

/// mainName must be the same as the method name
@pragma('vm:entry-point')
void pipMain() {
  runApp(YourApp());
}
