Flutter

Implementing a MapBox map in FlutterFlow with custom markers has never been easier. This enhanced version provides improved coordinate handling and a cleaner API structure. Start with the official MapBox documentation • create an account • and generate your public access token. Get Started | Maps SDK for Flutter | Mapbox Docs

Getting Your MapBox Access Token

Before diving into the code, you'll need to set up your MapBox account:

Create a MapBox Account: Visit mapbox.com and sign up for a free account
Navigate to Access Tokens: Once logged in, go to your account dashboard and find the "Access tokens" section
Create a Public Token: Generate a new public access token with the appropriate scopes for your application
Copy Your Token: Save this token securely as you'll need it for the widget configuration

Setting Up Your Custom Widget in FlutterFlow

Create a new custom widget in FlutterFlow and configure the essential parameters:

Name your custom widget CBMapBox and set up these parameters:

places (List<PlaceStruct>) - Your location data with nested LatLng coordinates
zoom (double) - Map zoom level for initial display
centerCoordinates (LatLng) - Single coordinate object for map center positioning
publicAccessToken (String) - Your MapBox public access token from the previous step
width (double, optional) - Widget width constraints
height (double, optional) - Widget height constraints
onClickMarker (Future Function, optional) - Callback function for handling marker interactions

Key Implementation Features

This enhanced MapBox integration includes several advanced features:

Smart Image Loading System

The widget intelligently handles both network URLs and local asset images • automatically detecting the source type • and converting images to the proper format for MapBox display.

Enhanced Coordinate Management

Instead of managing separate latitude and longitude values • the implementation uses a single LatLng coordinate object • providing cleaner data structure • and reducing parameter complexity.

Robust Marker Management

Dynamic marker creation and deletion • real-time updates when location data changes • and efficient memory management for large datasets.

Interactive Click Handling

Proper async event handling for marker clicks • state management for selected markers • and customizable callback functions for user interactions.

Data Structure Requirements

Your PlaceStruct should include:

latLng property of type LatLng containing latitude and longitude
imageUrl property for custom marker images (supports both network URLs and asset paths)
Any additional properties your application requires (name • description • category • etc.)

Map Configuration Options

The widget supports various MapBox styling options:

MapboxStyles.STANDARD - Modern • clean map appearance
MapboxStyles.LIGHT - Minimal styling for content overlay
MapboxStyles.DARK - Dark theme for night mode applications
MapboxStyles.SATELLITE - Satellite imagery view

Usage in Your FlutterFlow App

Once configured • the CBMapBox widget can be easily integrated into any page or component:

Add the Widget: Drag your custom CBMapBox widget onto your page
Configure Parameters: Set your places data • zoom level • center coordinates • and access token
Handle Interactions: Implement the onClickMarker callback to respond to user taps
Style Integration: Adjust width and height to fit your app's layout requirements

Performance Considerations

This implementation includes several performance optimizations:

Efficient Image Caching

Network images are properly cached • reducing redundant downloads • and improving map rendering speed.

Smart Marker Updates

Only updates markers when the places data actually changes • preventing unnecessary re-renders • and maintaining smooth user experience.

Memory Management

Proper cleanup of map resources • annotation managers • and image data to prevent memory leaks.

Advanced Customization Options

The widget architecture supports easy extension for additional features:

Custom Marker Clustering

Group nearby markers at lower zoom levels • improve performance with large datasets • and provide cleaner visual presentation.

Polylines and Polygons

Add route visualization • define geographic boundaries • and create interactive map overlays.

Real-time Updates

Integrate with live data sources • update marker positions dynamically • and provide real-time location tracking.

Custom Info Windows

Display detailed information on marker selection • create rich content overlays • and implement custom UI components.

Troubleshooting Common Issues

Access Token Problems

Ensure your token has the correct permissions • verify the token is active • and check that it's properly configured for your domain.

Image Loading Issues

Confirm image URLs are accessible • verify asset paths are correct • and ensure proper image formats (PNG • JPG) are used.

Performance Concerns

Limit the number of simultaneous markers • implement marker clustering for large datasets • and optimize image sizes for mobile display.

Final Thoughts

This enhanced MapBox implementation provides a robust foundation for location-based features in FlutterFlow applications. The improved coordinate handling • better error management • and modern styling options make it an excellent choice for production applications.

The architecture supports easy extension and customization • allowing you to build sophisticated mapping features without complex boilerplate code. Whether you're building a restaurant finder • delivery tracking app • or location-based social platform • this MapBox integration provides the flexibility and performance you need.
