onMessageReceived method

@override Future<void> onMessageReceived(JavaScriptMessage message)

接收JS消息

Implementation

@override
Future<void> onMessageReceived(JavaScriptMessage message) async {
  String? messageJson = message.message;
  Message messageItem = messageFromJson(messageJson);
  bool isResponseFlag = messageItem.isResponseFlag ?? false;
  if (isResponseFlag) {
    // 是返回的请求消息，则处理H5回调的值
    NativeBridgeHelper.receiveMessage(messageJson);
  } else {
    // 不是返回的请求消息，处理H5端的请求
    var callMethod = callMethodMap[messageItem.api];
    if (callMethod != null) {
      // 有相应的JS方法，则处理
      var data = await callMethod(messageItem.data);
      messageItem.data = data.toString();
    } else {
      // 若没有对应方法，则返回null，避免低版本未支持Api阻塞H5
      messageItem.data = null;
    }
    // 回调js，类型为回复消息
    messageItem.isResponseFlag = true;
    var json = messageToJson(messageItem);
    runJavaScript("receiveMessage($json)");
  }
