Hacky fixing overlaps about react-stack-grid

[berkayk]

I am not using hooks, is there any way that I can use this hack? I am currently using setState to set children to render but initial layout is overlapping. If I updateLayout 1 seconds later using setTimeout, it works.

@berkayk if you are using setState this means and async update is scheduled, so your previous render doesn't have the children? It depends on where you are calling setState, I would recommend putting the data which the grid depends on into props either in its parent component or extract it into a thin SFC with the hook above, which contains only that and other props which go to StackGrid

Im using this in children component and it works smoothly

https://github.com/maslianok/react-resize-detector

<StackGrid
  gridRef={grid => this.grid = grid} 
  columnWidth={width <= 768 ? '100%' : '33.33%'}
  gutterWidth={15}
  gutterHeight={15}
  monitorImagesLoaded={true}>         
  <ReactResizeDetector 
    handleWidth  
    handleHeight 
    onResize={() => {
      if (this.grid) {
        this.grid.updateLayout();
      }
    }}>
     <div>
        <img />
     </div>
  </ReactResizeDetector>
</StackGrid>

Instead of the requestanimationframe hack, you can use useRef to store a class variable.

const firstUpdate = useRef(true);
 useEffect(() => {
        if (firstUpdate.current) {
            firstUpdate.current = false;
            return;
        }
        if (grid.current) {
            grid.current.updateLayout();
        }
       
    }, [element.width, element.stack.sizes]);

That's very helpful. I tweaked the solution slightly to trigger grid.current.updateLayout each time an image's onLoad event was triggered, ensuring that delayed load times doesn't affect it. E.g.

  useEffect(() => {
    if( grid.current ){
      grid.current.updateLayout();
    }
  }, [imageLoadCounter])
