Flutter动态地图渲染插件atlas的使用

atlas

atlas 是一个可扩展的地图抽象库，支持多种地图提供商。

快速开始

设置

首先，需要设置 AtlasProvider 实例。这里以 CustomAtlas 为例：

import 'package:flutter/material.dart';
import 'package:atlas/atlas.dart';
import 'package:custom_atlas/custom_atlas.dart';

void main() {
  AtlasProvider.instance = CustomAtlas();
  runApp(MyApp());
}

使用

接下来，创建一个简单的应用来展示地图：

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Atlas Sample Demo',
      home: AtlasSample(),
    );
  }
}

class AtlasSample extends StatelessWidget {
  final CameraPosition _initialCameraPosition = CameraPosition(
    target: LatLng(
      latitude: 37.42796133580664,
      longitude: -122.085749655962,
    ),
    zoom: 12,
  );

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Atlas(
        initialCameraPosition: _initialCameraPosition,
      ),
    );
  }
}

添加标记

你还可以在地图上添加标记：

class AtlasSample extends StatelessWidget {
  final CameraPosition _initialCameraPosition = CameraPosition(
    target: LatLng(
      latitude: 37.42796133580664,
      longitude: -122.085749655962,
    ),
    zoom: 12,
  );

  final Set<Marker> _markers = Set.from([
    Marker(
      id: 'marker-1',
      position: LatLng(
        latitude: 37.42796133580664,
        longitude: -122.085749655962,
      ),
      icon: MarkerIcon(
        assetName: 'assets/marker.png',
      ),
      anchor: Anchor(
        x: 0.5,
        y: 1.0,
      ),
      onTap: () {
        print('tapped marker-1');
      },
    )
  ]);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Atlas(
        initialCameraPosition: _initialCameraPosition,
        markers: _markers,
      ),
    );
  }
}
