            How to stop Flutter Web HtmlElementView from rebuilding/rerunning?
            Asked 2020-Apr-24 at 23:40

            I have built a video calling app in Flutter using the Agora SDK. This is only available for iOS/Android and so for the web build I had to build a wrapper around the existing Agora web SDK. Due to the way Flutter renders web elements inside a shadow DOM, you cannot access elements by document.getElementById(), which is what the Agora SDK uses to inject their video player. To get around this I am rendering an IFrame that has the div and Agora SDK script bundled together.

            It is all working nicely but when any event is triggered inside the browser window, such as the mouse entering a button or clicking anything, the IFrame refreshes and rebuilds the video view which takes 1-2 seconds to initialize.

            Is there anyway I can unlink the IFrame from the browser events? I tried marking the HtmlElementView as const and putting it inside a StatefulWidget that only registers the platform view once. The widget isn't actually running the build() method again but the IFrame still refreshes.

            This is one of the active problem with the Flutter Web. I guess a workaround to this is mentioned here: https://github.com/flutter/flutter/issues/53253#issuecomment-607197549

            bad output of canvas generated image
            Asked 2018-Aug-11 at 21:36

            SO the code below is simply meant to allow users upload a video and then when the press the button 'choose thumbnail' an image is generated from a canvas which represents the current image which was showing when the video was playing...that is,the image becomes the thumbnail of the video which the user chooses by seeking a particular video time,pauses the video and creates the thumbnail which is an image of the video when it was paused.

            Everything is going fine except that the image is too long..in a way...the image is created in the dimensions that I want BUT some a lot of extra white space is still counted as the image....that is a lot of white space round it is the image.

            This screenshots may help...

            Cut the var c and var ctx declarations from //On clicking the Download button section and paste them with your other var declarations. This will give it global access (not just local access for only that specific function) :

            What is the most efficient way to clip a video running through canvas
            Asked 2017-Feb-10 at 14:56

            I have a situation where I need to clip either images or videos. The images or videos need to be able to overlap. We tried this originally with SVG, but for various reasons, that didn't work out well, so now we're doing it in Canvas.

            This worked out fine for images, but when it comes to videos, the browser is brought almost to a screeching halt after about 2 minutes. ( What you won't see from the sample code or link is that we are also pausing the video while it's not in view, and while the tab isn't in view. )

            Here is a link: http://codepen.io/paceaux/pen/egLOeR

            Of chief concern is this method:

            From comparing my code to how other people's code worked in this situation, I discovered that the flaw was in my drawFrame() method that I was using to actually draw the image from video into canvas.

            There were two fundamental problems:

            1. requestAnimationFrame() runs about 60fps, and because this is video, no more than 30 is needed
            2. I was drawing the clipping in every instance of drawFrame, and I didn't need to do that. You can clip the canvas once and then run requestAnimationFrame

            So, the new drawFrame method looks like this
