🚀 Quick Usage

🔹 Widget DSL

Text('Login')
  .paddingAll(16)
  .rounded(12)
  .backgroundColor(Colors.blue)
  .center()
  .onTap(() => print('Tapped'));

🔹 Iterable Widget DSL

[
  Icon(Icons.star),
  'Favorite'.text(),
].row(spacing: 8);

[
  'Welcome'.headlineMedium(context),
  'Please log in'.text(),
].column(crossAxisAlignment: CrossAxisAlignment.start, spacing: 16);

[
  'A'.text().backgroundColor(Colors.red),
  'B'.text().backgroundColor(Colors.green).expanded(),
  'C'.text().backgroundColor(Colors.blue).flex(2),
].row();

🔹 String → Text DSL

'Welcome'
  .text(fontSize: 18, fontWeight: FontWeight.bold);

'Title'.titleMedium(context);
'Body'.bodyMedium(context);
'Caption'.labelSmall(context);

🔹 Conditional Rendering

'Error occurred'
  .text()
  .visible(hasError);

'Edit'
  .text()
  .ifTrue(isEditable, orElse: () => Icon(Icons.lock));

🔹 Spacing DSL

Spacing(w: 12);             // Horizontal spacing
Spacing(h: 16);             // Vertical spacing
Spacing.square(24);         // Equal width & height
Spacing.none();             // Empty SizedBox
