I had just started learning flutter and I face a problem that now trying to solve it for three days.
Hope someone can help me.
The problem is that when I am trying to write a stateless widget, it should appear a short cut for it and click enter so it will automatic fill in all the code, but when I press enter it doesn't complete the code it only shows the word that I had written 'StatelessWidget' and of course it shows error with the red pulp.

I am still a beginner on Flutter, I don't understand why the warning lines still visible, there is no code yet, even when I tried to fill this screen, that's lines still visible
enter image description here
Hover mouse cursor on code & it will let you know what is causing the line to appear. Please share that message here.
Use snake_case for naming source files, like:
main_screen.dart, splash_screen.dart, or home.dart.
Keep caps lower and use underscores to separate words.
I have been trying not to have ask but I need some help. I am building my first flutter app. It's a calculator and I can get a basic one working without problems I am even getting it to evaluate with each key press, whether it be from my numbers widgets or by typing directly into the textfield.
I want to make it a bit different. I have tried to come up with the best way to do this but am not sure how. I want multiple sums to stay shown in the textfield(I presume if it needs editing I need to use a textfield) with the result attached. (i.e 2+6+4=12 then on a new line have another 6*6=36 etc.) At any time updating the textfield with the keypad must update all the sums on screen.
I have tried to do this using just one textfield (splitting the text and adding the sums to a list then calculating each and adding them back), however seems very cumbersome and I don't think this is the best approach. I have also made a Dynamic list of textfields , but found it difficult to index each textfield widget (dont think this is the correct approach) Im not asking for code but ideas as to which route to take. Your help would be appreciated.
I have been trying to not ask basic questions on stack overflow, but I cannot find a clue on the Internet related to this problem.
I wish to make my UILabel display multilines in my widget (Today Extension).
The "set lines to 0" solution works in the main app, but this doesn't seem to work within the widget. It keeps displaying only one line with '...' at the end.
Does anybody know how to resolve this issue? I will attach some screenshots to explain my problem further.
Increase the line limit number to 3 or more.
You can test the multiline wrapping by typing in the label yourself.
I know that setting it to '0' is suppose to work however when it comes to alerts and displays it does not always apply. I know that by giving it a number like '3' or '4' it is not dynamic, however, it will solve your problem with the notifications.
Alternatively you can use the "Autoshrink" feature, you can change it to minimum font size. By doing so, the application will shrink down the text to the font size you provided.
Some developers will also suggest checking the box, 'tighten letter spacing'
hope this helps.
I am making a form in ms-Access and needed buttons. A problem I am sure lots of you got is the flickering of certain button when going over them. I have searched around and found the same problem multiple time and never found the right answer.
People suggested things like changing labels to disabled textbox but it didn't work. I also tested it without anything else but buttons and it still does it. One of the first suggestion i actually found was disabling the theme, but still nothing. The latest tested suggestion was a pop-up window of the form and it still fail to fix the problem.
If you want to test it, just create a blank form and but multiple button. To see the effect more clearly, disable them all. Then go over them with your mouse multiple time and you'll eventually see the visual-glitch.
Is there reasons why those glitch happen? It seems to have been there for around 10 years. If you got a workaround, i would really appreciate it.
