LinearProgressWidget class

A customizable linear progress indicator widget with rounded edges.

Wraps Flutter's LinearProgressIndicator with additional customization options including custom colors, height, and rounded corners. Supports both determinate (specific progress value) and indeterminate (continuous animation) modes.

Features:

  • Customizable background and progress colors
  • Adjustable height
  • Rounded edges (8px border radius)
  • 8px padding around the indicator
  • Determinate or indeterminate progress modes

Example:

// Indeterminate progress (loading spinner)
LinearProgressWidget(
  determinate: false,
  progressColor: Colors.blue,
  backgroundColor: Colors.grey[300]!,
)

// Determinate progress (50% complete)
LinearProgressWidget(
  progress: 0.5,
  determinate: true,
  progressColor: Colors.green,
  height: 8.0,
)
