Styling Best Practices

How to style your app consistently and efficiently.

1. Use Themes: Define a global
ThemeData for your app to ensure consistency in colors, fonts, and component styles. Access it via
Theme.of(context).\n\n
2. Create a Style Guide: Define constants for colors, text styles, and spacing in a separate file (e.g.,
app_colors.dart,
app_text_styles.dart).\n\n
3. Extract Widgets: Don't bloat your
build methods with complex style configurations. Extract styled components into their own reusable widgets.

Code Example

// main.dart
MaterialApp(
  theme: ThemeData(
    primarySwatch: Colors.blue,
    scaffoldBackgroundColor: Colors.grey[100],
    textTheme: TextTheme(
      headline1: TextStyle(fontSize: 24, fontWeight: FontWeight.bold),
    ),
  ),
  home: HomePage(),
)

// In a widget
Text(
  'Styled Text',
  style: Theme.of(context).textTheme.headline1,
)
