draggable_panel 1.2.0

A versatile and customizable Draggable Panel

1.2.0

Desktop/Web resize stability, auto-docking, and controller improvements.

What's new

• Auto-dock on window resize: the draggable button now snaps to the nearest edge when the window is resized on desktop/web, matching the expected "перетягиваться в бока" behavior.
• Stable dock side: introduced isDockedRight in DraggablePanelController to track the docked side explicitly. This prevents side flipping during resizes and ensures consistent alignment when the button is off-screen.
• Resize handling in widget: DraggablePanel now observes didChangeMetrics and reclamps/repositions without long animations during resize.

Changes

• DraggablePanelController:
  • Added bool get isDockedRight and internal tracking updated in forceDock().
    • hidePanel(), togglePanel(), and toggleMainButton() now use isDockedRight instead of recomputing side from current left/width.
    • Added recomputeDockSide(pageWidth) helper for future scenarios where side needs recalculation without moving.
• DraggablePanel:
  • Uses controller.isDockedRight in UI instead of deducing side via left > width/2.
    • On init, initial position is clamped and, if closed, docked and panel hidden off-screen on the correct side.
    • On resize, positions are clamped, side is docked, and open/closed panel positions recalculated accordingly with zero-duration movement during the resize frame.

Fixes

• Panel and button no longer drift or jump when resizing the window; the open panel stays aligned to its edge, and the closed panel remains fully off-screen on the correct side.
• Prevented duplicate/misleading side calculations that caused inconsistencies during transitions.

Performance and cleanup

• Reduced unnecessary rebuilds during resize by batching updates and suppressing long animations for these events.
• Minor readability improvements (clearer border condition, removal of unused code, better ordering of resize operations).

Migration notes

• No breaking API changes. If you previously derived side from draggablePositionLeft, consider reading controller.isDockedRight for consistency with the new logic.

1.1.0

• Added: Position change listener API in DraggablePanelController (addPositionListener / removePositionListener).
• Added: Public dockBoundary getter for consistent boundary logic across widget and controller.
• Changed: toggle() now respects current panelState (not initialPanelState). Auto-toggle on mount removed to preserve user state. Initial position is clamped and (when starting closed) docked to the nearest edge.
• Fixed: Panel no longer resets to default after visibility toggles; duplicate position callbacks removed; unified docking logic.
• Performance: Batched x/y updates during drag via setPosition(x, y); reduced redundant notifications and rebuilds; lifecycle safety (mounted checks) and controller rewire in didUpdateWidget.

1.0.6

• Added tooltip snackbar when long press on the panel buttons and items.
• Records replaced by DraggablePanelItem and DraggablePanelButton models with description field for tooltips.

1.0.3

• Removed copy method from DraggablePanelController. It was not necessary. Issue was fixed by another way. Please if you use your own DraggablePanelController don't forget to dispose it.

1.0.2

• Added copy method to DraggablePanelController. It fixes the issue when you hide and re-show the panel.

1.0.1

• In this update, I added the DraggablePanelController to give you the ability to control the panel directly outside of this widget. Just create it and pass it to the DraggablePanel widget. See example.

1.0.0

• Changed alignment of Wrap inside DraggablePanel.

0.0.9

• Added new optional param panelHeight. This param is used to set the height of the panel. If not set, the panel will take the height of the child widget based on item's and button's length.

0.0.8

• The panel size calculation has been changed.

0.0.6

• Added web support with essential configuration for PWA functionality.
• Improved draggable panel logic by introducing better state management and optimizing boundary checks.
• Fixed issues with initial panel positioning and docking behavior.
• Simplified and cleaned up redundant code for better maintainability.

0.0.5

• Now child is nullable in DraggablePanel widget. This is useful when you want to use DraggablePanel inside other stack widgets.

0.0.4

• The DraggablePanelItem and DraggablePanelButton models were removed and replaced with Record. This was done to make the package easier to use. If you were using DraggablePanel in a package, you would need to import models for others that use your same package. Now, this is not necessary.

0.0.3

• Initial release.
