当错误消息出现时,它会降低高度TextFormField
。如果我理解正确,那是因为错误消息的高度正在考虑到指定的高度。
这是之前的屏幕:
之后 :
试图把conterText: ' '
到 BoxDecoration (正如我在另一个主题中看到的那样),但它没有帮助。
一个主意 ?
编辑:OMG 完全忘记放置代码,这里是:
return Form(
key: _formKey,
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.spaceEvenly,
children: <Widget>[
Container(
height: 40.0,
child: _createTextFormField(loginEmailController, Icons.alternate_email, "Email Adress", false, TextInputType.emailAddress),
),
Container(
height: 40.0,
child: _createTextFormField(loginPasswordController, Icons.lock, "Password", true, TextInputType.text),
),
SizedBox(
width: double.infinity,
child: loginButton
)
],
),
);
}
Widget _createTextFormField(TextEditingController controller, IconData icon, String hintText, bool obscureText, TextInputType inputType){
return TextFormField(
keyboardType: inputType,
controller: controller,
obscureText: obscureText,
/* style: TextStyle(
fontSize: 15.0,
), */
decoration: InputDecoration(
/* contentPadding:
EdgeInsets.symmetric(vertical: 5.0, horizontal: 8.0), */
border: OutlineInputBorder(borderRadius: BorderRadius.circular(5.0)),
icon: Icon(
icon,
color: Colors.black,
size: 22.0,
),
//hintText: hintText,
labelText: hintText,
),
validator: (value) {
if (value.isEmpty) {
return 'Enter some text';
}
return null;
},
);
}
