setGridFromBools method

void setGridFromBools(List<List<bool>> input)

Sets the grid of the Matrix object from a 2D list of boolean values.

This method takes a 2D list of boolean values representing the grid and converts it to the internal Uint8List representation.

Parameters: input (List<List<bool>>): The 2D list of boolean values representing the grid.

If the input grid is empty or has no rows, the Matrix is cleared.

Implementation

void setGridFromBools(final List<List<bool>> input) {
  if (input.isEmpty || input[0].isEmpty) {
    clear();
    return;
  }
  cols = input[0].length;

  // Create a new Uint8List to store the flattened grid data
  _matrix = Uint8List(input.length * cols);

  // Copy the input data into the flattened array
  for (int y = 0; y < rows; y++) {
    for (int x = 0; x < cols; x++) {
      cellSet(x, y, input[y][x]);
    }
  }
}
