This was really great... I can recount countless times in the past where if I had known this my life could have been so much more easier!

Nice one! But I have a question: you said that we can't get those values during the build, but if I need to resize some widget base on another widget, I think I need to do it during build proccess. Think about having an image and you need to know how much space it will fill and calculate other widgets based on this information. I dont know how to do it.

Thanks for one more very useful video! I really like your videos.

[aymenfayadhi]

Thank you so much for this tutorial !
Quick question : what if i want to get the size of a future widget inside a stream builder. where exactly should i call the "getSize" function knowing that it may lead to flickerin due to the setState();.
Thank in advance.

Hello Milke, nice content, very useful. I am wondering can we get current position of draggable widget with GlobalKey if we call the function for calculating in onDragStarted so we can calculate while it is dragged around?

How to paste the code in your tutorial is there any software ?...

[nitzaneliyahu]

I don't get it. Was render box changed recently in flutter? your code doesnt let me do this: final RenderBox box =
It says it should be RenderObject instead but then the rest of the code does not work with RenderObject so I am not sure what was changed?

It seems there is no updated version on how to find a widget size anywhere on the internet. Could you help? Thank you!

how to get Screen Size, width, height of device without mediaQuery.of(context) ? i want to draw a line for inside of specific widget, i don't know how to do it...

[mirshodbaxromov]

after upgrading flutter doesn't work RenderBox. Please update your video.

[aayushtheapple]

I got this error : The getter 'currentContext' isn't defined for the type 'Key'.
Try importing the library that defines 'currentContext', correcting the name to the name of an existing getter, or defining a getter or field named 'currentContext'.
What should I do ?
Please help!

I cant seem to get a RenderBox from a RenderObject, this works but size is not actually correct for me final renderBox = as RenderBox; So im getting 670 which isnt high enough, im starting to dislike flutter to be honest, absolutely awful at times, thanks for the videos though.
