Persistent callout

Is there a possibility of not having callout disappear?

I tried

        <MapView.Marker draggable ref="m2"
          onDragStop={(e) => this.setState({ startMarker: e.nativeEvent.coordinate })}
          onDragStart={(e) => this.refs.m2.showCallout()}
          coordinate={this.state.startMarker}
        >
          <MapView.Callout>
            <View>
                <Text>This is a plain view</Text>
              </View>
          </MapView.Callout>
        </MapView.Marker>

this still seems to be making a fade even on drag start and stop..
