I'm developing a timer application in Flutter and I've encountered an issue with restructuring my UI. Specifically, I need to move the start/pause button from the StartPomodoro
widget to a GNav
widget in my HomePageTimerUI
while maintaining the timer's functionality and controlling animations.
Here's the layout I currently have:
And here's what I'm aiming to achieve:
The challenge arises because my StartPomodoro
page contains all the logic for controlling the timer and animations. When I try to cut and paste the start widget into the HomePageTimerUI
, I can't seem to integrate it properly.
Here are the relevant parts of my code:
HomePageTimerUI.dart
class HomePageTimerUI extends StatefulWidget {
const HomePageTimerUI({Key? key}) : super(key: key);
@override
State<HomePageTimerUI> createState() => _HomePageTimerUIState();
}
class _HomePageTimerUIState extends State<HomePageTimerUI>
with TickerProviderStateMixin {
late TabController _tabController;
late Timer timer;
late AnimationController controller;
String get countText {
Duration count = controller.duration! * controller.value;
return controller.isDismissed
? '${controller.duration!.inHours.toString().padLeft(2, '0')}:${(controller.duration!.inMinutes % 60).toString().padLeft(2, '0')}:${(controller.duration!.inSeconds % 60).toString().padLeft(2, '0')}'
: '${count.inHours.toString().padLeft(2, '0')}:${(count.inMinutes % 60).toString().padLeft(2, '0')}:${(count.inSeconds % 60).toString().padLeft(2, '0')}';
}
@override
void initState() {
super.initState();
_tabController = TabController(length: 3, vsync: this);
}
@override
void dispose() {
_tabController.dispose();
super.dispose();
}
void notify() {
if (countText == '00:00:00') {
_tabController.animateTo(1, duration: const Duration(milliseconds: 300));
}
}
@override
Widget build(BuildContext context) {

How can I replace the start/pause button into the GNav
widget while maintaining its height and also initialize the timer correctly in this new structure?
Thank you for any assistance you can provide.

It's difficult to precisely figure out from the code produced. Because of too many widgets and wrong indentations. I would give suggestions based on rough insights.
If you want to seperate two elements use Spacer
that will do the job for you, Otherwise try the following approach.
Column
|_ Timer Container
|_ Floating button
to
Column
|_ Expanded
|_ Center
|_ Timer Container
|_ Floating Button
