SectionGridView class

SectionGridView is a widget for displaying a sections with grids.

Combines common grid functionalities from CommonGrid with features specific for a sectional layout.

Properties:

  • sections: The sections to display in the grid, each section containing its data and title.
  • renderItem: The function that renders each item in the grid.
  • itemSize: The size of the grid item. Defaults to 120.0, applicable when isFixed is false.
  • minItemDimension: The minimum dimension (width or height) of each grid item. Defaults to 120.0, applicable when isFixed is false.
  • verticalSpacing: The spacing between grid items vertically. Defaults to 10.
  • horizontalSpacing: The spacing between grid items horizontally. Defaults to 10.
  • itemsPerRow: The number of items per row in the grid. Defaults to 3, applicable when isFixed is false.
  • itemContainerStyle: Style of the container of each item in the grid. Defaults to ContainerStyle, applicable when isFixed is false.
  • isFixed: If true, uses the original size instead of adjusting to grid. Defaults to false.
  • horizontal: If true, the grid view grows horizontally. Defaults to false.
  • invertedRow: If true, inverts the order of the row. Defaults to false.
  • adjustGridToStyles: If true, adjusts the total dimensions of the grid based on style and container size. Defaults to false.
  • gridViewHeight: The height of the grid view. Defaults to 300.
  • gridViewWidth: The width of the grid view. Defaults to infinity.
  • containerWidth: The width of the main container. Relevant if greater than gridViewWidth. Defaults to infinity.
  • containerHeight: The height of the main container. Relevant if greater than gridViewHeight. Defaults to 300.
  • footerWidget: The widget rendered at the bottom of the grid view. Defaults to SizedBox.
  • physics: The physics of the grid view.
  • controller: ScrollController? to controll scroller in the grid view.
  • sectionController: List
  • onNewItemAdded: Callback function when a new item is added to the sections list.
  • onPressed: Callback function when an item in a section is pressed.
  • style: The style to apply to the section grid.
