Question

我正在尝试使用React本机视频播放全屏视频，如何在android和ios上全屏播放视频？对于风景模式，我使用了transform：[{rotation：'90deg'}]，它的工作原理是在android中将视频屏幕拉伸非常感谢您的帮助。
这是我的代码

    return (
        <View onLayout={this.onLayout.bind(this)} style={styles.fullScreen} key={this.state.key}>

            <View style={styles.backButtonWrapper}>
                <TouchableOpacity onPress={() => this.props.navigation.goBack()}>
                    <Image source={Share} />
                </TouchableOpacity>
            </View>

            <TouchableOpacity
                style={styles.videoView}
                onPress={this.playOrPauseVideo.bind(this, paused)}>

                <Video
                    ref={videoPlayer => this.videoPlayer = videoPlayer}
                    onEnd={this.onVideoEnd.bind(this)}
                    onLoad={this.onVideoLoad.bind(this)}
                    onProgress={this.onProgress.bind(this)}
                    source={{ uri: this.props.detailedWorkout.videoLink }}
                    paused={paused}
                    volume={Math.max(Math.min(1, volume), 0)}
                    resizeMode="none"

                {paused &&

                    <View style={styles.pauseImageWrapper}>
                        <Image style={styles.videoIcon} source={PlayButton} />
                    </View>
                }
            </TouchableOpacity>


        </View>
    );
}
const styles = StyleSheet.create({

    videoContainer: {
