Mapbox Maps Flutter SDK 在 iOS 與 Android 上的整合模式,涵蓋安裝、權杖、地圖、標註與 GeoJSON。

功能
此技能提供在 Flutter 應用程式中導入 mapbox_maps_flutter 套件的參考說明與程式碼模式。內容涵蓋安裝、iOS 與 Android 平台設定、存取權杖設定、MapWidget 初始化、相機控制、含點擊處理的標註管理器、使用者位置指示,以及從資源載入 GeoJSON。它也列出常見 iOS 建置與執行階段問題的排解步驟。此技能僅為說明文件,不附帶指令碼。
適用情境
適用於在 Flutter 專案中安裝或設定 mapbox_maps_flutter、設定 Mapbox 存取權杖、初始化 MapWidget、加入點、圓、線或多邊形標註、顯示使用者位置或載入 GeoJSON 的情境。也用於排解加入 Mapbox 後出現的 iOS 建置失敗。

Mapbox Flutter Integration Patterns

Official patterns for integrating the Mapbox Maps SDK for Flutter (mapbox_maps_flutter) on iOS and Android with Dart.

Use this skill when:

  • Installing and configuring mapbox_maps_flutter in a Flutter app
  • Setting the Mapbox access token the right way
  • Initializing a MapWidget with camera / style options
  • Adding annotations (points, circles, lines, polygons) and handling taps
  • Showing the user location puck
  • Loading GeoJSON from app assets
  • Troubleshooting iOS build failures after adding Mapbox

Official Resources:

Web and desktop are not supported — the Flutter SDK targets iOS and Android only.


Installation & Setup

Requirements

  • Flutter SDK 3.22.3 / Dart 3.4.4+
  • iOS: deployment target 14.0 or higher
  • Android: minSdk 21 or higher
  • Free Mapbox account

Step 1: Add the dependency

yaml
# pubspec.yamldependencies:  mapbox_maps_flutter: ^2.0.0
bash
flutter pub get

Step 2: Bump the iOS deployment target to 14.0 (required)

This is the single most common cause of iOS build failures after adding Mapbox. The Flutter SDK requires iOS 14.0 and will not compile on the Flutter default.

  1. Open ios/Runner.xcworkspace in Xcode.

  2. Select the Runner target → General → set Minimum Deployments → iOS to 14.0.

  3. If ios/Podfile exists, update the platform line too:

    ruby
    # ios/Podfileplatform :ios, '14.0'

You do not need to worry about CocoaPods vs Swift Package Manager — mapbox_maps_flutter supports both and Flutter picks whichever your app is configured for.

Step 3: iOS location permission

Add the purpose string to ios/Runner/Info.plist:

xml
<key>NSLocationWhenInUseUsageDescription</key><string>Show your location on the map</string>

Step 4: Android permissions

Add to android/app/src/main/AndroidManifest.xml:

xml
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /><uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />

Step 5: Configure the access token

The recommended pattern is to pass the token via --dart-define at build/run time and set it on MapboxOptions before creating any MapWidget.

bash
flutter run --dart-define=ACCESS_TOKEN=pk.your_token_here
dart
// main.dartimport 'package:flutter/material.dart';import 'package:mapbox_maps_flutter/mapbox_maps_flutter.dart';
const accessToken = String.fromEnvironment('ACCESS_TOKEN');
void main() {  MapboxOptions.setAccessToken(accessToken);  runApp(const MaterialApp(home: MapScreen()));}

Never hard-code tokens in source. For CI, pass --dart-define=ACCESS_TOKEN=$MAPBOX_ACCESS_TOKEN.


Map Initialization

Basic map

dart
import 'package:flutter/material.dart';import 'package:mapbox_maps_flutter/mapbox_maps_flutter.dart';
class MapScreen extends StatelessWidget {  const MapScreen({super.key});
  @override  Widget build(BuildContext context) {    return Scaffold(      body: MapWidget(        key: const ValueKey('mapWidget'),        cameraOptions: CameraOptions(          center: Point(coordinates: Position(-122.4194, 37.7749)),          zoom: 12,        ),        styleUri: MapboxStyles.STANDARD,      ),    );  }}

Grab the MapboxMap controller

dart
class MapScreen extends StatefulWidget {  const MapScreen({super.key});
  @override  State<MapScreen> createState() => _MapScreenState();}
class _MapScreenState extends State<MapScreen> {  MapboxMap? mapboxMap;
  void _onMapCreated(MapboxMap controller) {    mapboxMap = controller;  }
  @override  Widget build(BuildContext context) {    return MapWidget(      key: const ValueKey('mapWidget'),      onMapCreated: _onMapCreated,      cameraOptions: CameraOptions(        center: Point(coordinates: Position(-122.4194, 37.7749)),        zoom: 12,      ),    );  }}

Add Annotations

Use mapboxMap.annotations to create managers for point, circle, polyline, and polygon annotations. Managers are long-lived — create them once and reuse for updates.

Point annotations with a custom image

dart
import 'package:flutter/services.dart' show rootBundle;
PointAnnotationManager? pointAnnotationManager;
Future<void> _addMarkers(MapboxMap mapboxMap) async {  pointAnnotationManager = await mapboxMap.annotations.createPointAnnotationManager();
  final bytes = await rootBundle.load('assets/marker.png');  final imageBytes = bytes.buffer.asUint8List();
  final options = <PointAnnotationOptions>[    PointAnnotationOptions(      geometry: Point(coordinates: Position(-122.4194, 37.7749)),      image: imageBytes,      iconSize: 1.2,    ),    PointAnnotationOptions(      geometry: Point(coordinates: Position(-122.4094, 37.7849)),      image: imageBytes,    ),  ];
  await pointAnnotationManager!.createMulti(options);}

Remember to register the asset in pubspec.yaml:

yaml
flutter:  assets:    - assets/marker.png

Tap handling

Use manager.tapEvents — this is the current API. addOnPointAnnotationClickListener is deprecated.

tapEvents returns a Cancelable that you store and invoke .cancel() on when the listener is no longer needed:

dart
final Cancelable tapSubscription = pointAnnotationManager!.tapEvents(  onTap: (annotation) {    debugPrint('Tapped annotation ${annotation.id}');  },);
@overridevoid dispose() {  tapSubscription.cancel();  super.dispose();}

The same pattern — returning a Cancelable — exists on every manager's longPressEvents and dragEvents, and across the other annotation types (CircleAnnotationManager.tapEvents, etc.).

Load annotations from GeoJSON

dart
import 'dart:convert';import 'package:flutter/services.dart' show rootBundle;
Future<void> _loadGeoJson(MapboxMap mapboxMap) async {  final raw = await rootBundle.loadString('assets/coffee_shops.geojson');  final geo = jsonDecode(raw) as Map<String, dynamic>;  final features = (geo['features'] as List).cast<Map<String, dynamic>>();
  final manager = await mapboxMap.annotations.createPointAnnotationManager();  final icon = (await rootBundle.load('assets/coffee.png')).buffer.asUint8List();
  final options = features.map((feature) {    final coords = feature['geometry']['coordinates'] as List;    return PointAnnotationOptions(      geometry: Point(coordinates: Position(coords[0] as double, coords[1] as double)),      image: icon,    );  }).toList();
  await manager.createMulti(options);}

For thousands of features use a style layer (GeoJsonSource + SymbolLayer) instead of annotations.


Show User Location

Permissions must already be granted (use permission_handler or similar) before enabling the puck.

dart
await mapboxMap.location.updateSettings(LocationComponentSettings(  enabled: true,  puckBearingEnabled: true,  locationPuck: LocationPuck(    locationPuck2D: DefaultLocationPuck2D(),  ),));

Camera Control

dart
// Instant jumpawait mapboxMap.setCamera(CameraOptions(  center: Point(coordinates: Position(-80.1263, 25.7845)),  zoom: 14,));
// Animated fly-toawait mapboxMap.flyTo(  CameraOptions(    center: Point(coordinates: Position(-80.1263, 25.7845)),    zoom: 17,    bearing: 180,    pitch: 30,  ),  MapAnimationOptions(duration: 2000),);

Troubleshooting

iOS build fails with "platform is lower than deployment target"

The Flutter default iOS deployment target is lower than Mapbox's minimum (iOS 14). Set Minimum Deployments → iOS to 14.0 on the Runner target in Xcode. If the project has an ios/Podfile, also set platform :ios, '14.0' there and re-run pod install.

setAccessToken not called

If you forget to call MapboxOptions.setAccessToken before creating a MapWidget, the map will load with a blank grid. Always call it in main() before runApp.

Annotation tap handler not firing

Make sure you're using manager.tapEvents(onTap: ...) — addOnPointAnnotationClickListener is deprecated. Also confirm the MapboxMap controller is captured via onMapCreated before you create the annotation manager.

Hot reload after permissions change

iOS/Android will not re-read manifests or Info.plist on hot reload. Fully restart the app after editing permissions.
