Flutter Google Map GestureRecognizers

In Flutter, you can use the Google Maps plugin to integrate maps into your app.
The GestureRecognizers in Google Map help to handle various touch gestures like panning, zooming, and rotating the map.

Example: Enabling GestureRecognizers in Google Map

Import the Google Maps plugin in your Flutter app by adding it to the dependencies in the ‘pubspec.yaml’ file:

dependencies:
  flutter:
    sdk: flutter
  google_maps_flutter: ^1.0.9
  

Now, let’s see how to use GestureRecognizers in Google Map. Here’s an example of a basic implementation:

import 'package:flutter/material.dart';
import 'package:google_maps_flutter/google_maps_flutter.dart';

class MapScreen extends StatefulWidget {
  @override
  _MapScreenState createState() => _MapScreenState();
}

class _MapScreenState extends State {
  GoogleMapController mapController;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        title: Text('Google Map with GestureRecognizers'),
      ),
      body: GoogleMap(
        onMapCreated: (controller) {
          mapController = controller;
        },
        gestureRecognizers: Set()
          ..add(Factory(() => PanGestureRecognizer()))
          ..add(Factory(() => ScaleGestureRecognizer()))
          ..add(Factory(() => RotateGestureRecognizer())),
      ),
    );
  }
}
  

In the above example, we have created a `MapScreen` widget that extends `StatefulWidget`. Inside the build method, we use the `GoogleMap` widget from the `google_maps_flutter` package.
We provide an `onMapCreated` callback, where we assign the map controller to the `mapController` variable.
The `gestureRecognizers` property allows us to enable different gesture recognizers for the map. In this example, we enable panning, scaling, and rotating gestures using the `PanGestureRecognizer`, `ScaleGestureRecognizer`, and `RotateGestureRecognizer` respectively.

Remember to add the necessary permissions and API keys for Google Maps to work properly in your Flutter project.
