Answer 1

我认为您应该在 Android Studio 中指定 Java SDK 的路径，您可以通过执行以下操作进行设置：

<块引用>

一般来说，它是在“项目结构”对话框中设置的。

转到文件 > 项目结构 > SDK 位置。第三个字段是“JDK 位置”，您可以在其中进行设置。这将为当前设置项目。

Answer 2

试着给jdk设置一个符号，像这样

onPressed: ()=>{
if (_formKey.currentState!.validate()) {
   if(_password.length >= 6 && emailRegex.hasMatch(_email)){
      // put your code here!
   }
}

}
