问题 I am working with opencv on android for the development of an image segmentation application, but with the watershed algorithm. I am opening an image and creating a mask with the same image size and passing 0 for all the rows and columns of that mask.

问题 This only happens in iPhone-sized Safari. I am aware that the "usual fix" for this issue is to apply -webkit-transform: translate3d(0,0,0); (per Serge's answer here) and that does fix the issue, but only once. The issue occurs with a "drawer" menu that opens when the user clicks a menu button. The menu will show normally, but when it is touched/scrolled by a finger, the whole menu disappears from the page. Applying -webkit-transform: translate3d(0,0,0) fixes the issue, but only the first time

问题 I would like to disable the swipe back animation totally on a SPA. That would allow me to use some swiping gestures within the SPA.

They suggest following: 1) CSS only fix for Chrome/Firefox html, body { overscroll-behavior-x: none; } 2) JavaScript

问题 I'm trying to make something similar to google/apple maps screen in flutter. I just started experimenting in Flutter and I have a hard time understand that "Draggable widget". Could someone give me example code how they made their slide-up view, I can learn from?
