TextArea class

A multi-line text input widget with resizable dimensions and comprehensive styling.

TextArea provides an enhanced text editing experience with support for multi-line input, dynamic resizing capabilities, and extensive customization options. It supports both expandable height and width modes, allowing users to adjust the text area size by dragging resize handles.

Key features:

Multi-line text editing with optional height/width expansion
Configurable minimum and maximum dimensions
Support for leading and trailing widgets
Comprehensive text formatting and input validation
Integration with Flutter's text editing ecosystem
Customizable appearance through theming

The widget can operate in several resize modes:

Fixed size: When both expandableHeight and expandableWidth are false
Expandable height: When expandableHeight is true, allows vertical resizing
Expandable width: When expandableWidth is true, allows horizontal resizing
Fully expandable: When both expansion modes are enabled

Example:

TextArea(
  placeholder: Text('Enter your message...'),
  expandableHeight: true,
  minHeight: 100,
  maxHeight: 300,
  onChanged: (text) => print('Text: $text'),
);
