feat(location_plugin): 初始化位置插件项目

-结构和核心功能 添加了 Android 和 iOS 平台的 .gitignore 文件，排除构建产物和 IDE 配置文件- 创建了 Flutter 插件项目的基本目录结构和元数据配置
- 实现了获取当前设备位置的核心方法 getCurrentLocation
- 集成了华为地图 API 实现逆地理编码功能 getCityInfo
- 添加了权限配置和示例代码用于演示插件使用方式
- 编写了单元测试覆盖平台版本和位置获取功能- 配置了静态代码分析规则以确保代码质量

+# location_plugin
+
+A Flutter plugin that exposes:
+
+- `getCurrentLocation` — backed by native Android (Google Play Services) and iOS (CoreLocation) implementations, returning `{latitude, longitude}`.
+- `getCityInfo` — a Dart-side helper that calls Huawei Site reverse-geocode API to translate coordinates into city code and region names.
+
+## Usage
+
+```dart
+final plugin = LocationPlugin();
+
+final location = await plugin.getCurrentLocation();
+
+if (location != null) {
+  final lat = location['latitude'];
+  final lng = location['longitude'];
+
+  final cityInfo = await plugin.getCityInfo(latitude: lat!, longitude: lng!);
+  if (cityInfo != null) {
+    debugPrint('code=${cityInfo.code}, region=${cityInfo.region}');
+  }
+}
+```
+
+The plugin requests runtime permissions when required and surfaces any failures through `PlatformException`.
+
+## Permissions and configuration
+
+### Android
+
+- The plugin declares `ACCESS_FINE_LOCATION` and `ACCESS_COARSE_LOCATION` in its own manifest.
+- Ensure Google Play services are available on the target device.
+
+### iOS
+
+- Add `NSLocationWhenInUseUsageDescription` to your host app `Info.plist`.
+- The bundled `PrivacyInfo.xcprivacy` file declares the required-reason API entry for location (`L2`). Update it if your use case differs.
+
+## Example app
+
+The `example/` app fetches the current location on launch and provides a refresh button so you can validate the full flow end-to-end.
+
+## Implementation details
+
+- Android uses the fused location provider (`getCurrentLocation` with a fallback single update) when Google Play Services are available, and automatically falls back to the platform `LocationManager` on devices（如部分国内机型）缺少 GMS 的场景。
+- iOS relies on `CLLocationManager.requestLocation()` and listens for authorization changes before requesting a single fix.
+- `getCityInfo` posts `{lat, lng}` to `https://siteapi.cloud.huawei.com/mapApi/v1/siteService/reverseGeocode`. A default demo key is bundled; supply your own `apiKey` parameter in production and adjust error handling as needed.
+
+Feel free to extend the plugin with background tracking, geofencing, or reverse-geocoding as needed.

+Demonstrates how to use the location_plugin plugin.
+
+## Getting Started
+
+This project is a starting point for a Flutter application.
+
+A few resources to get you started if this is your first Flutter project:
+
+- [Lab: Write your first Flutter app](https://docs.flutter.dev/get-started/codelab)
+- [Cookbook: Useful Flutter samples](https://docs.flutter.dev/cookbook)
+
+For help getting started with Flutter development, view the
+[online documentation](https://docs.flutter.dev/), which offers tutorials,
+samples, guidance on mobile development, and a full API reference.

+# The following section is specific to Flutter packages.
+flutter:
+  # This section identifies this Flutter project as a plugin project.
+  # The 'pluginClass' specifies the class (in Java, Kotlin, Swift, Objective-C, etc.)
+  # which should be registered in the plugin registry. This is required for
+  # using method channels.
+  # The Android 'package' specifies package in which the registered class is.
+  # This is required for using method channels on Android.
+  # The 'ffiPlugin' specifies that native code should be built and bundled.
+  # This is required for using `dart:ffi`.
+  # All these are used by the tooling to maintain consistency when
+  # adding or updating assets for this project.
+  plugin:
+    platforms:
+      android:
+        package: com.touchme.location.location_plugin
+        pluginClass: LocationPlugin
+      ios:
+        pluginClass: LocationPlugin
+
+  # To add assets to your plugin package, add an assets section, like this:
+  # assets:
+  #   - images/a_dot_burr.jpeg
+  #   - images/a_dot_ham.jpeg
+  #
+  # For details regarding assets in packages, see
+  # https://flutter.dev/to/asset-from-package
+  #
+  # An image asset can refer to one or more resolution-specific "variants", see
+  # https://flutter.dev/to/resolution-aware-images
+
+  # To add custom fonts to your plugin package, add a fonts section here,
+  # in this "flutter" section. Each entry in this list should have a
+  # "family" key with the font family name, and a "fonts" key with a
+  # list giving the asset and other descriptors for the font. For
+  # example:
+  # fonts:
+  #   - family: Schyler
+  #     fonts:
+  #       - asset: fonts/Schyler-Regular.ttf
+  #       - asset: fonts/Schyler-Italic.ttf
+  #         style: italic
+  #   - family: Trajan Pro
+  #     fonts:
+  #       - asset: fonts/TrajanPro.ttf
+  #       - asset: fonts/TrajanPro_Bold.ttf
+  #         weight: 700
