writeTextConfig method

int writeTextConfig({ required VectorGraphicsBuffer buffer, required String text, required String? fontFamily, required double xAnchorMultiplier, required int fontWeight, required double fontSize, required int decoration, required int decorationStyle, required int decorationColor, })

Write the text contents given starting at x, y.
