NineTileBox.withGrid constructor

NineTileBox.withGrid(Sprite sprite, { double leftWidth = 0.0, double rightWidth = 0.0, double topHeight = 0.0, double bottomHeight = 0.0, })

Creates a nine-box instance with the specified grid size

A nine-box is a grid with 3 rows and 3 columns. The outer-most columns, leftWidth and rightWidth, are a fixed-width. As the nine-box is resized, those columns remain fixed-width and the center column stretches to take up the remaining space. In the same way, the outer-most rows, topHeight and bottomHeight, are a fixed-height. As the nine-box is resized, those rows remain fixed-height and the center row stretches to take up the remaining space.

Implementation

NineTileBox.withGrid(
  this.sprite, {
  double leftWidth = 0.0,
  double rightWidth = 0.0,
  double topHeight = 0.0,
  double bottomHeight = 0.0,
}) : tileSize = sprite.src.width ~/ 3 {
  destTileSize = tileSize;
  center = Rect.fromLTWH(0, 0, sprite.src.width, sprite.src.height);
  _dst = Rect.fromLTWH(0, 0, sprite.src.width, sprite.src.height);
  setGrid(
    leftWidth: leftWidth,
    rightWidth: rightWidth,
    topHeight: topHeight,
    bottomHeight: bottomHeight,
  );
}
