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()),);Get Value like:
String email=emailEditingController.text;
