RxList extends List，not recommended

[YueLiXing]

class TempService extends GetxService {
  final message = <String>[].obs;
  
  setMessage(List<String> newMessages) {
    message.value = newMessages;
  }
  
  Future<void> loadMessage() async {
    final temp = ['123'].obs;
    setMessage(temp);
  }
}

When you use it this way, there will be no error or warning prompts, but exceptions will occur at runtime because assigning the value of one Rx object to another Rx value。

Hello, here are the docs about How to use Lists

You SHOULD NEVER use list.value = newValue.

Use AssignAll (or assign) methods.

Using your exemple:

class TempService extends GetxService {
  final message = <String>[].obs;
  
  setMessage(List<String> newMessages) {
    message.assignAll(newMessages);
  }
  
  Future<void> loadMessage() async {
    final temp = ['123'].obs;
    setMessage(temp);
  }
}

I hope it helps.
