OffsetSnappingModel constructor

const OffsetSnappingModel(
  1. Set<double> offsets
)

Constructs a OffsetSnappingModel with the specified offsets.

  • offsets: A set of pixel values representing snapping positions. These values should typically be greater than or equal to 0.0 and less than or equal to the maximum pixel height of the sheet's viewport.

Usage Example:

// Define sheet height snapping positions at 100px, 300px, and 600px with a viewport size of 800px.
final snappingModel = OffsetSnappingModel({200.0, 500.0, 700.0});

Explanation:

Given a viewport height of 800px:

  • An offset of 700px means the sheet will snap to a position 100px from the bottom (800 - 700 = 100).
  • An offset of 500px means the sheet will snap to a position 300px from the bottom (800 - 500 = 300).
  • An offset of 200px means the sheet will snap to a position 600px from the bottom (800 - 200 = 600). This allows for intuitive placement of the sheet at specific offset from the top of the screen.

Implementation

const OffsetSnappingModel(this.offsets);
