Code

Import master_validator package to your dart widgets by writing:

import 'package:master_validator/master_validator.dart';

This makes the MasterValidator class available in your codespace

Basic Required Field Validation

TextFormField(
    validator: MasterValidator.attach(
        flags: [ValidatorFlags.Required]
    ),
),

Email Validation

TextFormField(
    validator: MasterValidator.attach(
        flags: [ValidatorFlags.Required, ValidatorFlags.Email],
        msgPrefix: "Email",
    ),
),

Note : By Default all validator flags support non required field, which means that if the field has an email validator flag but doesn't have the required flag with it, it wouldn't give an error message if the textfield is empty, to change this behaviour, use MasterValidator.requiredAnd, for Example

TextFormField(
    validator: MasterValidator.requiredAnd(
        flag: ValidatorFlags.Email,
        msgPrefix: "Email",
    ),
),
