react-native - React Native Maps - takeSnapshot 不捕获标记

Question

react 原生:https://github.com/expo/react-native/archive/sdk-42.0.0.tar.gz
react :16.13.1
react 原生 map :0.28.0
我想将标记作为快照的一部分。当我们使用 takeSnapshot方法所有标记都被忽略。

const snapshot = this.viewRefTest.takeSnapshot({
  format: 'png', // image formats: 'png', 'jpg' (default: 'png')
  quality: 0.5, // image quality: 0..1 (only relevant for jpg, default: 1)
  result: 'file', // result types: 'file', 'base64' (default: 'file')
});

<MapView
  ref={(viewRefTest) => {
    this.viewRefTest = viewRefTest;
  }}
  showsUserLocation={true}
  followUserLocation={true}>
  <MapView.Marker coordinate={item.location}>
    <Image
      style={{ width: 30, height: 30 }}
      source={require('../../assets/images/trophy.png')}
    />
    <Callout style={{ width: 250, flexDirection: 'row', alignItems: 'center' }}>
      <Text>$23</Text>
      <View>
        <Text style={{ fontSize: 12 }}>Custom Text!</Text>
      </View>
    </Callout>
  </MapView.Marker>
</MapView>;

请让我知道这种可能性。

您可以尝试使用宽度和高度吗？

const snapshot = this.viewRefTest.takeSnapshot({
  width: 500,
  height: 500,
  format: 'png',
  quality: 0.5,
  result: 'file',
});

snapshot.then((uri) => {
  console.log(uri);
});
