I have a TextFormField inside an Alert Dialog which is supposed to close only after the TextFormField value has been validated or show an Error Message in case no input was provided. However, as things stand, the button doesn't seem to work at all regardless of whether I have input or not. Just to add, I intend to launch the Facebook Sign In Screen as soon as Continue is pressed after providing an input. Can someone tell me what I'm doing wrong?

QUESTION
I am trying to show an alert dialog which contains a loading animation. The Alert dialog needs to appear after clicking another alert dialog that was initially in display. Basically,the first dialog contains a setPositive and setNegative button. The setPositive event is triggers a process which takes a few seconds. I wanted the second dialog containing the loading animation to appear when the process begins. I am not able to dismiss the first dialog until the process is done for the loading dialog to show.

QUESTION
everyone! I'm begging for help. I have a StatefulWidget in which I call AlertDialog, created initState and setState, but button colour changes only if I close and reopen AlertDialog, not immediately when clicked. I need to figure out how to redraw this window or some other way. There's another problem, if I put the FloatingActionButton in a separate file and therefore in a separate StatefulWidget, the list itself doesn't update when I click Add, but if I put the FloatingActionButton back in the homepage, everything works. But that's an additional question) A big request for help with the ElevatedButton "Work" inside the AlertDialog.
...ANSWER
Answered 2022-Mar-04 at 17:31The dialog box does not update itself using set state. So you have to use other state managements like GetX or Provider to change the state of the widget. Secondly it will also help update the value you want to update using the button.
QUESTION
Hi i think i don't really now how live data works.
I am having a 2D Array with prefilled Values.
...ANSWER
Answered 2022-Feb-19 at 19:14Seeing the new state after a screen rotation (after a configuration change) is not related to how LiveData works. You are observing your LiveData correctly.
So i want that only the current State of my Array and no future states are pushed to my LiveData Objects so i gave it a copy of my Array.
A slight correction here, you gave it a shallow copy of your array. A shallow copy is a copy of the original array, but if the items are instances (references to objects), they will be copied by reference. Which means that changes on items in the copy of the array will affect the items in the original array as well, since it is the same references (= same instances).
And since you have an array of arrays, items in your array are instances of 4 other arrays. And when you change the values inside randomboard in your trySetValue function, you access the same 4 array instances every time.
The arrayOf calls create a new array instance and fill it with the values provided as parameters. So your initial assignment to randomboard creates 5 array instances:
- 4 are of type Integer[] and contain values 0, 0, 0, 0
- 1 is of type Integer[][] and contains references to the 4 arrays above. The reference to this array is stored into the field
randomboards
This snippet of code compares the values by reference and shows that the main array is a new instance (because of the copyOf call), but the arrays inside are the same instances.
QUESTION
Some functions take a long time to execute. I want to make the user wait with a progress bar. Unfortunately, when I run this one, it runs but only at the end of my function and not when I would like. Let me explain, I launch my progress bar with the "sendloading()" method but during my tests this bar is only displayed after the processing of the other functions "copyAssets" or "createOnClicBtnInsert()". Can someone explain to me why?
Here is my code :
...ANSWER
Answered 2022-Feb-07 at 16:00Android is an event driven OS that runs on a single main thread. Drawing is an event. That means in order to draw the main thread needs to return to the event loop. Your code does not return to the event loop until after you do all your processing. Thus it won't draw until after the processing is done.
The way to solve this is to use either a Thread or a Kotlin coroutine to do the processing, and allow the main thread to return to the event loop. BTW, if you have long lasting processing you should not be doing it on the main thread anyway- it freezes your UI and makes your app appear non responsive, for the same reason. The main thread should do short quick calculations and respond to OS events only.
QUESTION
I have a List that is populated with the return data of various var's called by a Json API
This List also has a fixed Text element preceding the data
I want to have separate weight, size etc for the initial text and then the String being passed in
I have tried RichText and TextStyle but needed a text function, not a list for it to work correctly
Here is the List, which is then passed into a function which pushes it to ShowDialog via the dynamic message
For example, Line: to be FontWeight.w600 & $pln String to be FontWeight.w400
