Usage

For more complete example open App.tsx

import MapViewGestures from 'react-native-maps-draw';
import type { TTouchPoint } from 'react-native-maps-draw';
import MapView, { Polygon, Marker } from 'react-native-maps';

const AnimatedPolygon = Animated.createAnimatedComponent(Polygon);

export default function App() {
  const mapRef = useRef<MapView>(null);

  const convertByPoint = async (item: any) =>
    await mapRef.current?.coordinateForPoint(item);

  const handlePolygon = useCallback(
    (_: any, index: number) => (
      <AnimatedPolygon
        key={index}
        coordinates={polygon.polygons}
        fillColor="rgba(255, 171, 171, 0.01)"
        strokeColor="rgba(255, 171, 171, 0.88)"
        strokeWidth={1}
      />
    ),
    [polygon.polygons]
  );


  return (
    <SafeAreaView style={styles.container}>
      <MapView ref={mapRef} style={styles.map} onMapReady={handleMapReady}>
        {...rest}
      </MapView>

      {... && (
        <MapViewGestures
          points={points}
          widthLine={3}
          colorLine={'green'}
          onEndDraw={handleCanvasEndDraw}
          onChangePoints={setPoints}
          backgroundCanvas={'rgba(0, 0, 0, 0.0)'}
          convertByPoint={convertByPoint}
        />
      )}
    </SafeAreaView>
  );
