I like how the search bar on my iPhone’s safari is below and the box gets bigger and smaller in real time when I scroll, so it doesn’t bother me when I scroll down, but I can’t find a way to implement it. I think it’s an attractive UI that I can keep checking the content you search below
Which widget should I use? How should I implement it?
I used SliverPersistentHeaderDelegate to implement it with the floating property of SliverPersistentHeader, and I couldn’t implement logic such as not only being fixed on top, but also getting bigger and smaller boxes.
