📱 如何使用

  1. 申请百度appkey:
  1. 安装:
dependencies:
  flutter:
    sdk: flutter
  bmap_map_fluttify: ^x.x.x
  1. 导入:
import 'package:bmap_map_fluttify/bmap_map_fluttify.dart';
  1. 使用:
/// !!使用真机调试!!
/// !注意: 只要是返回Future的方法, 一律使用`await`修饰, 确保当前方法执行完成后再执行下一行, 在不能使用`await`修饰的环境下, 在`then`方法中执行下一步.
/// 
/// android端的appkey需要在AndroidManifest.xml中配置, 详见 http://lbsyun.baidu.com/index.php?title=androidsdk/guide/create-map/showmap
await BmapService.init(iosKey: '7a***********************f4');
/// 如果你觉得引擎的日志太多, 可以关闭Fluttify引擎的日志
await enableFluttifyLog(false); // 关闭log

class BmapWidget extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return BmapView(
      // 缩放级别 (可选)
      zoomLevel: 10, 
      // 中心点坐标 (可选)
      centerCoordinate: LatLng(39, 116),
      // 地图创建完成回调 (可选)
      onMapCreated: (controller) async {
        // requestPermission是权限请求方法, 需要你自己实现 
        // 如果不知道怎么处理, 可以参考example工程的实现, example工程依赖了`permission_handler`插件.
        if (await requestPermission()) {
          // 请开始你的表演
        }
      },
    );
  }
}

requestPermission的参考实现(需要依赖permission_handler插件):

import 'package:decorated_flutter/decorated_flutter.dart';
import 'package:permission_handler/permission_handler.dart';

Future<bool> requestPermission() async {
  if ((await Permission.location.request()).isGranted) {
    return true;
  } else {
    // 处理授权失败的情况
    toast('需要定位权限!');
    return false;
  }
}

iOS Info.plist配置:

<!--使用PlatformView的声明-->
<key>io.flutter.embedded_views_preview</key>
<string>YES</string>
<!--定位权限声明-->
<key>NSLocationWhenInUseUsageDescription</key>
<string>需要定位权限</string>
<!--这个是app在桌面显示的名称 百度地图要求必须有这个键值对-->
<key>CFBundleDisplayName</key>
<string>百度地图测试</string>
  1. 说明
  • ios端添加marker时会出现日志暂不支持有返回值的回调方法, 这个可以忽略, 因为已经通过手写代码处理了.
  • 插件中所有的方法都集中在BmapControllerBmapService中, BmapControllerBmapWidget创建完成时返回, 用来操作地图. BmapService中全都是静态方法, 不直接涉及地图组件的方法都放在这个类中, 比如初始化, 其他的各种计算等.
