flutter插件开发

# pigeon使用

# 开发流程

开发具体流程可见:

https://juejin.cn/post/7006554771674906637

以plugin的模式创建,以自动初始化

 flutter create --template=plugin --platforms=android,ios -i swift -a java --org com.hss01248 location_util

拷贝根目录下pigeon/schema.dart文件夹和run_pigeon.sh文件到根目录

修改pigeon/schema.dart方法定义

修改run_pigeon.sh里目标路径.

dev_dependencies:
  pigeon: ^1.0.0

运行run_pigeon.sh.无日志则生成代码成功.

# 写Android和ios实现

# 注册pigeon

public class LocationUtilPlugin implements FlutterPlugin, MethodCallHandler {

  private MethodChannel channel;

  @Override
  public void onAttachedToEngine(@NonNull FlutterPluginBinding flutterPluginBinding) {
    channel = new MethodChannel(flutterPluginBinding.getBinaryMessenger(), "location_util");
    channel.setMethodCallHandler(this);

   //上面是模板生成的,下面是自己手动注册:
  LocationPigeon.LocationUtil.setup(flutterPluginBinding.getFlutterEngine().getDartExecutor().getBinaryMessenger(), new LocationImpl());
  }

# 入参

类型安全 or json/map?

# 返回值

参考后台接口返回: data,code,msg形式, 不抛出exception,而是以code,msg形式返回.

msg在debug时返回整个堆栈,在release时返回友好的翻译信息

# exception处理

需要await才能catch住

try{
	await  _flipperNetworkPlugin.reportRequest(uniqueId,DateTime.now().millisecondsSinceEpoch,
      '${options.baseUrl}${options.path}',options.method,headers,body);
}catch(e,s){
  debugPrint("print by dio-flutter: reportRequest--> "+e.toString());
  //+s.toString()
}
