pv_grid_edit 0.0.1

building snapped grid editors with draggable and resizable shapes.

pv_grid_edit

A Flutter package for building snapped grid editors with draggable and resizable rectangle shapes.

Features

• Rectangle-based grid editing with frozen, fixed-size movable, constrained, and free-flowing behaviors.
• Collision rollback for non-overlapping shapes.
• JSON serialization for layouts and shapes.
• A simple dictionary helper for map-based load and save boundaries.

Getting started

Add the package to your pubspec.yaml, then create a GridEditorBloc and pass it to GridEditor.

Usage

final bloc = GridEditorBloc(
	initialLayout: GridLayout(
		shapes: <GridShape>[
			GridRectangleShape.constrained(
				id: 'panel',
				position: const GridPoint(column: 0, row: 0),
				size: const GridSize(columns: 3, rows: 2),
			),
		],
	),
);

For map-based integration, use GridEditorMapHelper.layoutFromDictionary(...) and GridEditorMapHelper.dictionaryFromLayout(...).
