Flutter: Password Check - flutter

Question

I will enter the password to the user 2 times. but i don't know how to check this. How can I be sure that both passwords are spelled the same? can i do this?
here is my code,(I just put the relevant parts in order not to be long)
class _RegisterPageState extends State<RegisterPage> {
#override
Widget build(BuildContext context) {
return Scaffold(
body: SafeArea(
child: SingleChildScrollView(
child: Column(
children: [
_paddingPasswordWidget('Password', 'Password'),
_paddingPasswordWidget('Password Again', 'Password Again'),
],
),
),
),
);
}
}
_paddingPasswordWidget(String hintTextStr, String labelTextStr) {
return Padding(
padding: EdgeInsets.only(top: 15, left: 22, right: 22),
child: TextFormField(
keyboardType: TextInputType.text,
style: TextStyle(
color: HexColor('#868686'),
),
decoration: CommonInputStyle.textFieldStyle(
hintTextStr: hintTextStr,
labelTextStr: labelTextStr,
),
obscureText: true,
),
);
}
class CommonInputStyle {
static InputDecoration textFieldStyle(
{String labelTextStr = "", String hintTextStr = ""}) {
return InputDecoration(
contentPadding: EdgeInsets.only(left: 20, top: 5, bottom: 5, right: 20),
labelText: labelTextStr,
hintText: hintTextStr,
labelStyle: TextStyle(fontSize: 14, color: HexColor('#868686')),
hintStyle: TextStyle(fontSize: 14, color: HexColor('#868686')),
filled: true,
fillColor: HexColor('#EEF2F4'),
border: OutlineInputBorder(
borderRadius: BorderRadius.circular(16),
borderSide: BorderSide.none,
),
);
}
}

You can try putting textEditingController in your fields, then you compare them. Something like this:
var textFieldPasswordController = TextEditingController();
var textFieldConfirmPasswordController = TextEditingController();
then you pass these as controllers in your TextFormField:
TextFormField(
controller: textFieldPasswordController //as an example
keyboardType: TextInputType.text,
style: TextStyle(
color: HexColor('#868686'),
),
Now you just need to check if textFieldPasswordController.text equals to textFieldConfirmPasswordController.text. You can check this in the onChange or validator function of TextFormField
if(textFieldPasswordController.text == textFieldConfirmPasswordController.text){
print("Access granted");
} else{
print("Try again");
}
