android - Flutter 在调试时抛出错误 - 编译器消息：lib/views/signUp.dart:1:8: Error: Not found: 'dart:html' import 'dart:html';

Question

Flutter 版本 1.17.4 我正在使用Android Studio 4.0使用macOS 10.15.5的 Mac

Android Studio 4.0 Build #AI-193.6911.18.40.6514223，于 2020 年 5 月 20 日构建

输入以下代码行后，编码运行顺利，调试时出现此错误。

signMeUp() {
    if (formKey.currentState.validate()) {
      setState(() {
        isLoading = true;
      });
      authMethods.signUpWithEmailAndPassword(
          emailTextEditingController.text, passwordTextEditingController.text);
    }

当前的错误如下所示，我向那里的任何人寻求帮助，这是我的第一次颤抖，我进展不顺利。
