MapZoneManager

MapZoneManager is a Flutter package that provides a widget and controller to manage zones on a Google Map. It allows you to create, update, and manage multiple zones, with features for handling map markers, polygons, and custom actions like adding or resetting zones. It supports both single and multi-zone management and is highly customizable with features like custom buttons and map styles.

Features

• Zone Creation: Create zones by tapping on the map and adding coordinates to form a polygon.
• Multiple Zones: Supports managing multiple zones on the map.
• Customizable: Customize zone colors, border colors, and border width.
• View-Only Mode: Ability to display zones in a read-only mode (no zone creation).
• Custom Buttons: Option to replace the default add/reset zone buttons with custom widgets.
• Markers & Polygons: Displays markers and polygons for each zone created on the map.
• Zoom Controls: Enable/disable zoom controls and gestures.
• Location Services: Enable location tracking and display of the user's current location.
• Map Styles: Apply different map styles to customize the appearance of the map.

          multiZone: true,
          showAddButton: true,
          showResetButton: true,

MapZoneManagerController

The MapZoneManagerController is a controller class for managing zones and map-related operations. You can use this controller to manage zones, add coordinates, and move the camera to fit a zone.

MapZoneManagerController controller = MapZoneManagerController(
  onZoneAdded: (zone) {
    print('New Zone Added: ${zone.zoneId}');
  },
  multiZone: true,
);

controller.createZone();
controller.addPositionOnCurrentZone(LatLng(37.7749, -122.4194));
