RenderTexture constructor

RenderTexture(
  1. int width,
  2. int height,
  3. int fillColor
)

Implementation

RenderTexture(int width, int height, int fillColor) {
  if (width <= 0) throw ArgumentError('width');
  if (height <= 0) throw ArgumentError('height');

  _width = width;
  _height = height;
  _source = _canvas = CanvasElement(width: _width, height: _height);

  if (fillColor != 0) {
    final context = _canvas!.context2D;
    context.fillStyle = color2rgba(fillColor);
    context.fillRect(0, 0, _width, _height);
  }
}
