Getting Started 🚀

Installation

Add this to your pubspec.yaml:

dependencies:
  ai_profanity_textfield: ^1.0.0

Quick Start 🏃

ProfanityTextFormField(
  geminiService: geminiService, // Your Gemini service instance
  decoration: InputDecoration(
    hintText: 'Enter text here...',
  ),
  onProfanityDetected: (text) {
    print('Profanity detected in: $text');
  },
)

Custom Validators ✨

Add your own validation rules alongside AI profanity detection!

ProfanityTextFormField(
  geminiService: geminiService,
  checkWhileTyping: true,
  debounceDuration: const Duration(milliseconds: 500),
  validators: [
    (value) => value.isEmpty ? 'Required field' : null,
    (value) => value.length < 3 ? 'Too short' : null,
    (value) => !value.contains('@') ? 'Must contain @' : null,
  ],
  onProfanityDetected: (text) => print('Profanity detected!'),
  onCleanText: (text) => print('Text is clean and valid'),
  decoration: InputDecoration(
    hintText: 'Type something...',
    fillColor: Colors.white,
    border: OutlineInputBorder(
      borderRadius: BorderRadius.circular(18),
    ),
  ),
  showValidIcon: true,
  profanityMessage: 'Oops! Let\'s keep it friendly 😊',
  validationMessageDuration: const Duration(seconds: 3),
)

Validation Process 🔄

1. Custom validators run first in the order they are defined
2. If all custom validations pass, AI profanity check runs
3. Text is considered valid only when both custom validations and profanity check pass

Multilingual Example 🌐

ProfanityTextFormField(
  geminiService: geminiService,
  decoration: InputDecoration(
    hintText: '여기에 텍스트를 입력하세요...', // Korean
    // or '在此输入文字...' // Chinese
    // or 'Écrivez ici...' // French
    // etc.
  ),
  profanityMessage: 'Lütfen nazik olalım! 😊', // Turkish
  validators: [
    // Custom validators work with any language!
    (value) {
      if (value.length < 5) {
        return '最小5文字必要です'; // Japanese error message
      }
      return null;
    },
  ],
)

Advanced Features 🔧

Real-time Validation ⚡

The widget validates text as users type, with a customizable debounce duration:

ProfanityTextFormField(
  geminiService: geminiService,
  checkWhileTyping: true,
  debounceDuration: Duration(milliseconds: 500),
  validators: [
    // Custom validators run in real-time too!
    (value) => value.length < 3 ? 'Too short!' : null,
  ],
  onCleanText: (text) {
    print('Text is clean and valid: $text');
  },
)

Custom Styling 🎨

Make it match your app's theme:

ProfanityTextFormField(
  geminiService: geminiService,
  successDecoration: InputDecoration(
    fillColor: Colors.green,
    border: OutlineInputBorder(
      borderRadius: BorderRadius.circular(18),
    ),
  ),
  profanityDecoration: InputDecoration(
