集成easy_geofencing后geolocator依赖出现Android编译错误求助

问题背景 #

我有一个基于Flutter的项目，原本使用geolocator: ^9.0.2实现位置获取功能，核心定位代码如下：

Map mreturn;
bool serviceEnabled;
LocationPermission permission;

serviceEnabled = await Geolocator.isLocationServiceEnabled();
if (!serviceEnabled) {
  Location location = new Location();
  serviceEnabled = await location.serviceEnabled();
  if (!serviceEnabled) {
    serviceEnabled = await location.requestService();
    if (!serviceEnabled) {
      mreturn = {"status": 0, "message": 'Location Denied once'};
      return mreturn;
    }
  }
}

permission = await Geolocator.checkPermission();
if (permission == LocationPermission.denied) {
  permission = await Geolocator.requestPermission();
  if (permission == LocationPermission.denied) {
    mreturn = {"status": 0, "message": 'Location permissions are denied'};
    return mreturn;
  }
}

if (permission == LocationPermission.deniedForever) {
  mreturn = {
    "status": 0,
    "message":
        'Location permissions are permanently denied, we cannot request permissions.'
  };
  return mreturn;
}

Position position = await Geolocator.getCurrentPosition();
mreturn = {"status": 1, "message": "Location Received", "position": position};
return mreturn;

集成easy_geofencing: ^0.2.0实现地理围栏功能后，出现如下编译错误：

/Users/lasthoney/.pub-cache/hosted/pub.dartlang.org/geolocator_android-2.1.0/android/src/main/java/com/baseflow/geolocator/permission/PermissionUtils.java:27: warning: [deprecation] getPackageInfo(String,int) in PackageManager has been deprecated
              .getPackageInfo(context.getPackageName(), PackageManager.GET_PERMISSIONS);
              ^

* What went wrong:

解决方案 #

方法一：强制升级geolocator_android依赖版本 #

错误根源是easy_geofencing: ^0.2.0依赖的geolocator版本较低（^7.0.0），导致项目自动降级了geolocator_android到2.1.0，该版本包含已废弃的Android API方法，触发编译警告并被转为错误。

在项目的pubspec.yaml中添加依赖覆盖，强制使用兼容geolocator: ^9.0.2的geolocator_android版本：

dependency_overrides:
  geolocator_android: ^4.1.0

执行flutter pub get更新依赖后重新编译。

方法二：关闭Android编译的警告转错误机制 #

在项目的android/build.gradle文件中，修改lintOptions配置，禁止将警告视为错误：

android {
    // 保留原有其他配置
    lintOptions {
        abortOnError false
    }
}

方法三：升级easy_geofencing到最新版本 #

查看easy_geofencing的最新版本，若新版本已更新geolocator依赖到兼容版本，直接在pubspec.yaml中升级easy_geofencing的版本号，再执行flutter pub get即可解决依赖冲突问题。
