A text input field with validation, theming, and advanced features.

TTextField provides a fully-featured text input with support for:

  • Single-line and multi-line input
  • Validation rules with debouncing
  • Required field indicators
  • Helper text and placeholders
  • Disabled and read-only states
  • Custom theming
  • Value binding with ValueNotifier

Basic Usage

TTextField(
  label: 'Email',
  placeholder: 'Enter your email',
  isRequired: true,
  rules: [
    Validations.required('Email is required'),
    Validations.email('Invalid email format'),
  ],
  onValueChanged: (value) => print('Email: $value'),
)

Multi-line Text Area

TTextField(
  label: 'Description',
  rows: 5,

With Value Notifier

final emailNotifier = ValueNotifier<String?>('');

TTextField(
  label: 'Email',
  valueNotifier: emailNotifier,
)
