Renders this object. Called by markerPainter

Implementation

@override
void render(UiRenderContext renderContext) {
  MappointRelative relative = renderContext.projection.latLonToPixel(latLong).offset(renderContext.reference);
  Offset offset = Offset(relative.dx, relative.dy);
  // Draw the circle
  renderContext.canvas.expose().drawCircle(offset, 20, _paint);

  // Prepare the text
  _textPainter.text = TextSpan(
    text: _clusterText,
    style: const TextStyle(color: Colors.white, fontSize: 16, fontWeight: FontWeight.bold),
  );
  _textPainter.layout();

  // Center the text inside the circle
  final textOffset = offset - Offset(_textPainter.width / 2, _textPainter.height / 2);

  // Draw the text
  _textPainter.paint(renderContext.canvas.expose(), textOffset);
