Usage Examples

Basic Length Constraints

Enforce minimum and maximum length requirements for patterns:

Dart

import 'package:prettier_reg_exp/prettier_reg_exp.dart';

void main() {
  final regex = PrettierRegExp(minLength: 3, maxLength: 5).generate();
  print(regex.hasMatch('abc'));  // true (matches 3 characters)
  print(regex.hasMatch('abcdef')); // false (exceeds 5 characters)
}

Email Validation

Generate a regex specifically for validating email addresses:

Dart

import 'package:prettier_reg_exp/prettier_reg_exp.dart';

void main() {
  final regex = PrettierRegExp(isEmail: true).generate();
  print(regex.hasMatch('[e-mail]')); // 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")
}
