Its true that the 10% is the most difficult.. Tips and trick needed.
Been working on a project for about 6 months now. Still learning flutter and dart as i go. Took a break for a month, because of overworking and now im back. I really want to finish this project because i feel that its still very promising and i see a market for something like this.I've been quite overwhelmed by learning eveything from firebase, cloud functions, webscraping, how to structure communication from client- to server and the other way around to not get lost in my own code. The whole app is based on online features so its essential that it works correctly.Now, i'm on the last features i want to finish and polish but i'm really stuck in this procrastinate period because i lost my mojo when i took the break. I've been thinking about trying to find help like looking for freelancer with more experience in firebase and flutter but it's been hard trying to find anyone that have experience with this.Any tips or tricks you have when getting stuck in a period like this, what do you usually do? Also where would you recommend to look if you would like to look for help in your project?

Is it right to set a fixed width for button?
Hi guys,My question is about the right method for designing an app that can perform in various screen sizes. For example; setting the width of buttons as 300.0 on a screen may be problematic? What is the right way to have widgets that seems perfect regardless of screen size?

How to force ScrollController to recalculate position.maxExtents?
Does anyone know the answer to this question?
https://stackoverflow.com/questions/60855712/flutter-how-to-force-scrollcontroller-to-recalculate-position-maxextents=====================================================================I'm trying to create a desktop-style scrollbar, that changes it's size based on the size of the content.My scrollbar shares a ScrollController with a list, and relies on the position.maxExtents to know how large the content area is.The issue is that when I change the number of rows, the maxExtents will not update, until a scrollEvent is initiated.I've worked around it with code like this, moving 1px up, and 1px down over 100ms:
widget.controller.jumpTo(controller.position.pixels + 1); Future.microtask(() => widget.controller.animateTo(controller.position.pixels - 1, duration: 100.milliseconds, curve: Curves.linear)); 
Which works pretty quite well when the list can scroll. However, when the list is < the height of the view, it can't scroll, and these calls have no effect, and I'm stuck with a stale maxExtents.How can I just tell the list: Hey, list, recalculate your children!

Disabling forms or Modal Progress Indicator
I've been making progress with flutter using Udemy and at one point in Andrea's course, he suggests a challenge to disable the forms while it's saving. Earlier in the course, it was just disabled with a TODO for the indicator. I looked up the Modal Progress HUD, built my own and now I'm left wondering:TLDRIf a modal barrier on the stack can prevent interaction with the layer below, is it still necessary or perhaps best practice to disable the forms and buttons? It seems unnecessary to me.
