InputSpinnerFeature class

Adds spinner controls (increment/decrement) to numeric input fields.

Provides up/down buttons to adjust numeric values in fixed steps. Optionally supports gesture-based adjustments (e.g., drag to change value).

Example:

TextField(
  keyboardType: TextInputType.number,
  features: [
    InputSpinnerFeature(
      step: 5.0,
      enableGesture: true,
    ),
  ],
)
