QUESTION
As the title above, I want the page I've scrolled down to scroll back up when the BottomNavigationBar is pressed (double-pressed). I've managed to make it, no problem. But there is a problem if on the page there is contain a TabBar.
For Example I have a bottom navigation bar, that contains two pages:
HomePage
and ProfilePage
On the HomePage I have a TabBar, and that contains two pages also:
FirstTabBarView
and SecondTabBarView
The problem is when I've scrolled those two pages down (HomePage & ProfilePage at a different) I just want the FirstTabBarView view page to scroll to the top if I'm currently opening the FirstTabBarView page. But from my code, if I press the BottomNavigationBar button twice, both FirstTabBarView and SecondTabBarView both scroll up.
This is just a simple code sample, you can copy-paste and test it on the dart pad directly
...ANSWER
Answered 2022-Mar-29 at 04:27You will have to lift up the TabController along with the scrollcontrollers. Then use the TabController's index getter to check which tab is currently open.
QUESTION
I am currently localizing my app, I have translates all the webpages to be opened and added the url to my arb files.
But when i call the AppLocalizations.of(context)!.actionaid
on initialUrl
i get a red underline saying Invalid constant value
Is there any way I could make this work?
Thanks guys
I have something like this:
...ANSWER
Answered 2022-Mar-24 at 00:23The problem is that you are defining your Widget tree to only contain constant values by writing const CupertinoPageScaffold
.
Since AppLocalization.of(context).actionaid
is not providing a constant value this "rule" gets violated and triggers the error.
Changing const CupertinoPageScaffold
to just CupertinoPageScaffold
or extracting the WebView
widget into a separate widget with a const constructor should do the trick.

Imagine I have a parent widget and a child widget. In the parent widget, there is a variable: 'page index'. And the child widget needs to change that variable in a set state method (because it has to be refreshed). How can I do this?

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
As the title mentions, I'm currently creating a guitar application that is to include some information on basic notes and chords, a chord generator, and of course a guitar tuner. I've decided to start with what I believe is the hardest part and unfortunately making little to no progress.
I'd like to include a BottomNavigationBar to navigate between these three tools, each taking up one page. I can get the navigation to work while using StatelessWidget, but once I start using _TunerState for recording purposes I start receiving errors.
I've managed to get this tool working in a separate application using just the main.dart but integrating that solution into my project is proving difficult.
What I intend to do is use the _TunerState class to initialize and start the flutter_fft recorder, which will listen for changes in the mic input and output information such as frequency, note, etc.
Below is my home_widget.dart, in charge of the navigation, or at least that's what I'm trying to do with it
...ANSWER
Answered 2021-Dec-29 at 21:41In your tuner.dart File the _TurnerState extends the Sate
but it needs to extend for example class _TunerState extends State
