Email Validation

Dart
import 'package:prettier_reg_exp/prettier_reg_exp.dart';

void main() {
final regex = PrettierRegExp(isEmail: true).generate();
print(regex.hasMatch('[email protected]')); // true (valid email format)
print(regex.hasMatch('invalid-email')); // false (invalid format)
}

Custom Patterns with Constraints
Define a regex with tailored constraints:
Dart
import 'package:prettier_reg_exp/prettier_reg_exp.dart';

void main() {
final regex = PrettierRegExp(
customPattern: r'^[a-zA-Z0-9]{8,12}$', // 8-12 alphanumeric characters
mustContain: ['abc'], // Must include "abc"
mustNotContain: ['xyz'], // Must not include "xyz"
).generate();

print(regex.hasMatch('abcdefgh')); // true (matches constraints)
print(regex.hasMatch('abcdxyz')); // false (violates "mustNotContain")
}
