Demonstrated in this repo:

• Main App Scaffold
  • a responsive scaffold that changes from tab bar + drawer, to a combined side-menu for larger screens
  • children are shared between widgets showing how you can reuse the same widget in multiple places
• A custom title bar is implemented for all platforms using a single widget
  • VisualDensity is controlled with a button inside the title bar, and changes density across the entire app
  • VisualDensity button is right-aligned on macOS to not conflict with native window controls
• AdaptiveGrid uses LayoutBuilder to create a responsive grid,
  • //TODO: shows cross platform multi-select behavior
  • //TODO: shows popups and right-click menu to delete
  • //TODO: shows select all and delete behavior
• AdaptiveDataTable uses LayoutBuilder to add/remove columns in a table, depending on space available
• AdaptiveReflow uses LayoutBuilder to reflow between 3 different layout types: Vertical, Horizontal and Mixed.
