TimelineTheme class

Theme configuration for Timeline widgets.

Provides styling and layout defaults for timeline components including column constraints, spacing, indicator appearance, and connector styling. Used with ComponentTheme to apply consistent timeline styling across an application while allowing per-instance customization.

Example:

ComponentTheme<TimelineTheme>(
  data: TimelineTheme(
    timeConstraints: BoxConstraints(minWidth: 100, maxWidth: 150),
    spacing: 20.0,
    dotSize: 16.0,
    color: Colors.blue,
    rowGap: 24.0,
  ),
  child: MyTimelineWidget(),
);
