"Password & confirm pass is not same" Validation in flutter with TextEditingController is-CodePudding

I want to Check First Password & Confirm Password is the same or not if Not Showing the message is not the same. And if it's the same Call the API to Update this Password.

For this, I am applying some Conditions In "If Else" but it's not working Because of TextEditingController.

Here is my code If you can suggest to me some ideas?

use Regex

static const Pattern PASSWORD_VALIDATE_REGEX =
      r'^(?=.*?[A-Z])(?=.*?[a-z])(?=.*?[0-9])(?=.*?[!@#\$&*~]).{8,}$';

String passwordPattern = Constants.PASSWORD_VALIDATE_REGEX;
  RegExp passwordRegExp;

passwordRegExp = RegExp(passwordPattern);
        if (value.trim().isEmpty) {
          return AppStrings.CONFIRM_PASSWORD_EMPTY_ERROR;
        } else if (!passwordRegExp.hasMatch(value)) {
          return AppStrings.CONFIRM_PASSWORD_INVALID_ERROR;
        } else if (value != _passwordController.text) {
          return AppStrings.PASSWORD_DIFFERENT_ERROR;
        }
        return null;

Instead of your way you can use Form widget and validator to do this. Try this:

class MyHomePage extends StatefulWidget {
  MyHomePage({
    Key? key,
  }) : super(key: key);

  @override
  _MyHomePageState createState() => new _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final _formKey = GlobalKey<FormState>();
  TextEditingController passController = TextEditingController();
  TextEditingController confermPassController = TextEditingController();

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(),
      body: Column(
        children: [
          Form(
            key: _formKey,
            child: Column(
              children: [
                TextFormField(
                  controller: passController,
                ),
                TextFormField(
                  controller: confermPassController,
                  validator: (value) {
                    if (passController.text != confermPassController.text) {
                      return 'pass and conferm pass is not the same';
                    }
                    return null;
                  },
                ),
              ],
            ),
          ),
          SizedBox(
            height: 40,
          ),
          InkWell(
            onTap: _formKey.currentState != null &&
                    _formKey.currentState!.validate()
                ? () {
                    //call your api hear;
                  }
                : null,
            child: Text('call Api'),
          ),
        ],
      ),
    );
  }
}
