获取多个文本字段值的最佳方法

使用TextFormField中的控制器，您可以获取TextFormField的值。

TextEditingController emailEditingController = TextEditingController();TextFormField(  controller: emailEditingController,  validator: (value) {    if (value.isEmpty) {      return 'Please enter a valid email address';    }    if (!value.contains('@')) {      return 'Email is invalid, must contain @';    }    if (!value.contains('.')) {      return 'Email is invalid, must contain .';    }    return null;  },  keyboardType: TextInputType.emailAddress,  decoration: InputDecoration(      prefixIcon: Icon(Icons.mail_outline),      labelText: 'Enter Email',      border: OutlineInputBorder()),);
