Dynamic dashboard widget that allows your users to create their own layouts. Rezise, move, indirect resize/move, auto re-layout are supported.


Try online demo

Dashboard can be thought of as a dynamic grid. Your users can create their own layouts, add new widgets or remove widgets.

Layout divides the screen into horizontal slots according to the entered value. The aspect ratio of the slots also determine their height. Widgets called DashboardItem are placed in these slots. This layout can be changed later.


Dashboard Items can be resized both by long pressing on mobile and by holding and moving on desktop/browser.


Dashboard Item locations can be changed by long pressing on mobile or by holding and pulling on desktop/browser.

Slots Changes

With dynamic slot count, you can re-layout window size changes.


Storage Delegate

The layout information of the users can be stored in the database or on the local disk.

Define your storage delegate.

class MyItemStorage extends DashboardItemStorageDelegate {  

  FutureOr<List<DashboardItem>> getAllItems(int slotCount) {  
    // return items from db.
  FutureOr<void> onItemsUpdated(  
      List<DashboardItem> items, int slotCount) {
      // save new layouts to db.

And use it.

    itemStorageDelegate: MyItemsStorage())

Getting started

Define Dashboard

  dashboardItemController: itemController,  
  itemBuilder: (item) {
	//return widget

Define Items

Items can come from the database, or can be defined as fixed.


DashboardItemController(items: [
  DashboardItem(width: 2, height: 3, identifier: "id_1"),  
      startX: 3, startY: 4, width: 3, height: 1, identifier: "id_2"),  

Or with delegate:

    itemStorageDelegate: MyItemStorage())

See example

Define Builder

The Builder is invoked with a DashboardItem and returns a widget.

  dashboardItemController: itemController,  
  itemBuilder: (item) {
	return Text(item.identifier);


Item Style

Each item is wrapped with a Material widget. You can enter the parameters of the Material widget with item style.

All is optional.

  color: Colors.red,  
  borderRadius: BorderRadius.circular(10),  
  shape: const RoundedRectangleBorder(),  
  shadowColor: Colors.black,  
  animationDuration: const Duration(milliseconds: 200),  
  borderOnForeground: false,  
  clipBehavior: Clip.antiAliasWithSaveLayer,  
  elevation: 10,  
  textStyle: const TextStyle(color: Colors.black),  
  type: MaterialType.card  


Slide to top items initially. Auto relayout places items to top as possible.

slideToTop: true






Shrink items when re-layout or editing is possible.

Edit Mode Settings

See code comments for edit mode settings parameters.

All is optional.


        // animation settings
        curve: Curves.easeInOutCirc,
        duration: const Duration(milliseconds: 200),
        // fill editing item actual size
        fillEditingBackground: true,

        // space that can be held to resize
        resizeCursorSide: 20,
        // draw lines for slots
        paintBackgroundLines: true,
        // shrink items when editing if possible and necessary
        shrinkOnMove: true,
        // long press to edit
        longPressEnabled: true,
        // pan to edit
        panEnabled: true,
        backgroundStyle: const EditModeBackgroundStyle(
            fillColor: Colors.red,
            lineWidth: 1.5,
            lineColor: Colors.black,
            // line by vertical space
            dualLineHorizontal: true,

            // line by horizontal space
            dualLineVertical: true));
