A comprehensive, opinionated collection of high-quality Flutter widgets designed for building enterprise-grade applications with speed and consistency.

te_widgets provides a robust set of UI components, form builders, and layout utilities that adhere to a unified design system.

📦 Installation

Add this to your pubspec.yaml:

dependencies:
  te_widgets: ^2.0.4

🚀 Getting Started

1. Setup Theme

Wrap your application with the TTheme extensions or configure your ThemeData to utilize te_widgets defaults.

import 'package:te_widgets/te_widgets.dart';

MaterialApp(
  theme: ThemeData(
    extensions: [
      TWidgetThemeExtension.light, // Or .dark
    ],
  ),
  // ...
);

2. Basic Layout

Use TLayout to quickly scaffold a responsive application structure with a sidebar.

TLayout(
  logo: TLogo(text: 'My App'),
  items: [
    TSidebarItem(icon: Icons.dashboard, text: 'Dashboard', route: '/'),
    TSidebarItem(icon: Icons.settings, text: 'Settings', route: '/settings'),
  ],
  child: MyPage(),
);

3. Building a Form

Use TFormBuilder to create robust forms with validation.

class UserForm extends TFormBase {
  final name = TFieldProp('');
  final email = TFieldProp('');
  final role = TFieldProp<String?>(null);

  @override
  List<TFormField> get fields => [
    TFormField.text(name, 'Full Name', isRequired: true),
    TFormField.text(email, 'Email Address', 
      rules: [Validations.email('Invalid email')]
    ),
    TFormField.select<String, String, String>(
        role, 
        'Role',
        options: ['Admin', 'User', 'Guest'],
        itemText: (item) => item,
        itemKey: (item) => item,
    ),
  ];
}

// In your widget:
final form = UserForm();

// Show as a modal
TFormService.show(context, form);

4. Data Tables

Create sophisticated tables with minimal code.

TDataTable<User, int>(
  headers: [
    TTableHeader.text('ID', (user) => user.id.toString()),
    TTableHeader.text('Name', (user) => user.name),
    TTableHeader.chip('Status', 
      (user) => user.status, 
      color: (user) => user.isActive ? Colors.green : Colors.red
    ),
  ],
  onLoad: (options) async {
    // Fetch data from API based on options.page, options.search, etc.
    return await fetchUsers(options);
  },
);
