From this question Flutter: How to use Wrap instead of ListView.builder? , I am creating a wrap widget like this. It work well but using 100ms to render the ui.

Wrap(
  alignment: WrapAlignment.spaceBetween,
  children: [
    for (var i in _items)
      Text('Item $i'),
    // spacer to make last line space between
    const Spacer(),
    const Spacer(),
  ],
)

reduce the items to render , <=1000 it work well, however if 3000 or 5000 take too much time to render.
