▶️ How To Develop a UI Kit with Flutter | Use BigKit UI + Best Materials for Fast & Stunning Results
🚀 Why Create a Flutter UI Kit?
- Speed up development. A custom UI kit means you never reinvent the wheel—drag, drop, and tweak.
- Ensure consistency. One theme, one style guide, everywhere.
- Scale effortlessly. New screens, new apps—simply plug in your components.
- Showcase professionalism. Clients and users love a smooth, cohesive design.
🔧 Prerequisites
- Flutter SDK installed (check Flutter docs for setup)
- Basic Dart knowledge
- Familiarity with Material Design (see material.io/design for guidelines)
- A code editor (VS Code, Android Studio, etc.)
🛠 Step-by-Step: Building Your UI Kit
1. Set Up Your Project
flutter create my_ui_kit
cd my_ui_kit
- Initialize a Git repo.
- Add BigKit UI to your
pubspec.yaml:dependencies: flutter: sdk: flutter bigkit_ui: ^1.0.0 - Run
flutter pub get.
2. Define Your Color Palette & Typography
- Create a file at
lib/theme/app_theme.dart. - Use Material’s
ColorSchemeandTextTheme:import 'package:flutter/material.dart'; final ColorScheme appColorScheme = ColorScheme.fromSeed(seedColor: Colors.indigo); final TextTheme appTextTheme = Typography.material2018().black;
Pro Tip: Stick to 5–7 primary colors for clarity and brand consistency.
3. Build Core Widgets
Leverage BigKit UI’s prebuilt widgets, then customize:
import 'package:bigkit_ui/bigkit_ui.dart';
class PrimaryButton extends StatelessWidget {
final String label;
final VoidCallback onPressed;
PrimaryButton({required this.label, required this.onPressed});
@override
Widget build(BuildContext context) {
return BigkitButton(
text: label,
onTap: onPressed,
type: BigKitButtonType.primary,
);
}
}
- Buttons: Primary, secondary, ghost
- Cards: Info, image, profile
- Lists & Grids: Vertical lists, horizontal carousels
- Navigation: Bottom nav bars, tabs, drawers
4. Organize Your Folder Structure
lib/
├── components/ # Reusable widgets
├── theme/ # Color, typography, spacing
├── pages/ # Example screens
├── utils/ # Helpers & extensions
└── main.dart
Good structure = better maintainability.
5. Create Example Screens
Showcase each component in isolation:
class ButtonDemoPage extends StatelessWidget {
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(title: Text('Buttons Demo')),
body: Center(
child: PrimaryButton(label: 'Click Me', onPressed: () {}),
),
);
}
}
Link to them from a home page to allow quick previews.
6. Add Animations & Interactions
- Use Flutter’s built-in AnimationController for subtle fades and slides.
- BigKit UI includes
BigkitAnimatedContainer—perfect for micro-interactions.
BigkitAnimatedContainer(
duration: Duration(milliseconds: 300),
curve: Curves.easeInOut,
child: MyCustomCard(),
);
7. Performance Optimization
- Hot reload speeds up iteration; use it obsessively.
- Split large widgets into smaller ones to minimize rebuilds.
- Use
constconstructors where possible. - Test UI performance with Flutter’s DevTools.
