Expanded(
child: CloudWidget(
child: Text(
'ABCDEFGHIJKLMNOPQRSTUVWXYZ',
softWrap: false, // Prevents text from wrapping to the next line
overflow: TextOverflow.ellipsis, // Handles overflow with '...' truncation

1. Why Expanded?
The expanded widget guarantees that Text (and its ancestor CloudWidget) occupies available space in a Row, Column, or Flex layout.
Otherwise, lengthy text can lead to a layout overflow (e.g., "Right Overflowed by 42 pixels").
2. TextOverflow Options
Select how to manage overflow:
TextOverflow.ellipsis (. at the end).
TextOverflow.fade (blurs text out).
TextOverflow.clip (hard cut, no visual indication).
TextOverflow.visible (renders beyond the widget bounds—use with care!).
3. softWrap: false
4. Best Practices
Always limit text in a Row/Column with Expanded or Flexible.
Include semantic labels if the text is cut off (for accessibility):
Semantics(
label: 'Full text: ABCDEFGHIJKLMNOPQRSTUVWXYZ',
child: Text(/*. */),
)
When to Use This Pattern
Horizontal space constraints: Tabs, buttons, or list items, e.g.
Dynamic content: User-provided text that could be too lengthy.
Accessibility: Use with Semantics for screen readers.
Common Pitfalls
Not including Expanded/Flexible → Overflow errors occur.
Not including softWrap: false → TextOverflow won't be invoked.
Not supporting RTL (Right-to-Left) languages → Test using lengthy Arabic/Hebrew text.
