I wanted to make a page which shows a timer of 2 minutes and then the users can click on the button and move on to the next page. So for this I used the TweenAnimationBuilder and it works properly as long as the timer is not 0. As soon as it becomes zero it gives the following error.
======== Exception caught by widgets library =======================================================
The following _CastError was thrown building TweenAnimationBuilder<num>(duration: 120000ms, dirty, state: _TweenAnimationBuilderState<num>#9c4a1(ticker inactive)):
type 'int' is not a subtype of type 'double' in type cast
The relevant error-causing widget was:
TweenAnimationBuilder<num> TweenAnimationBuilder:file:///C:/Users/Vedant/StudioProjects/activepeers_app_internship/lib/introduction/introPage.dart:60:13
When the exception was thrown, this was the stack:

====================================================================================================
======== Exception caught by rendering library =====================================================
The following assertion was thrown during layout:
A RenderFlex overflowed by 99781 pixels on the bottom.
The relevant error-causing widget was:
Column Column:file:///C:/Users/Vedant/StudioProjects/activepeers_app_internship/lib/introduction/introPage.dart:32:16
The overflowing RenderFlex has an orientation of Axis.vertical.
The edge of the RenderFlex that is overflowing has been marked in the rendering with a yellow and black striped pattern. This is usually caused by the contents being too big for the RenderFlex.
Consider applying a flex factor (e.g. using an Expanded widget) to force the children of the RenderFlex to fit within the available space instead of being sized to their natural size.
This is considered an error condition because it indicates that there is content that cannot be seen. If the content is legitimately bigger than the available space, consider clipping it with a ClipRect widget before putting it in the flex, or using a scrollable container rather than a Flex, like a ListView.
The specific RenderFlex in question is: RenderFlex#5298b relayoutBoundary=up2 OVERFLOWING
... needs compositing
... parentData: offset=Offset(0.0, 0.0) (can use size)
... constraints: BoxConstraints(0.0<=w<=392.7, 0.0<=h<=803.6)
... size: Size(392.7, 803.6)
... direction: vertical

Reloaded 19 of 804 libraries in 1,051ms.
So since it said type 'int' in not a subset of type 'double' I changed the variables to num but still this error is coming.
This is my code-
import 'package:flutter/material.dart';
import 'package:activepeers_app_internship/quizScreens/quiz_screen.dart';
class IntroPage extends StatefulWidget {
const IntroPage({Key? key}) : super(key: key);
@override
State<IntroPage> createState() => _IntroPageState();
}
class _IntroPageState extends State<IntroPage> {
@override
Widget build(BuildContext context) {
return Scaffold(
body:
Center(
child: Column(
children: [
SizedBox(
height: 70,
),
Padding(padding: EdgeInsets.all(16),
child: Image.asset("assets/logo3.png", fit: BoxFit.cover)),
SizedBox(
height: 70,
),
Text(
"Introduction",
style: TextStyle(
fontSize: 32,
fontWeight: FontWeight.bold,
),
),
SizedBox(
height: 20,
),
Text("Take a couple minutes to\n introduce yourselves.",
style: TextStyle(
fontSize: 26,
),
),
SizedBox(
height: 70,
),
TweenAnimationBuilder(
tween: Tween(begin: 120.0, end: 0),
duration: Duration(seconds: 120),
builder: (context, value, child) {
num val = value as double;
num time = val;
num min = (time/60).floor();
num sec = (time`).floor();
return Text(
sec>=0 && sec<10?"$min:0$sec":"$min:$sec",
style: TextStyle(
fontSize: 80,
fontWeight: FontWeight.bold,
),
);
},
onEnd: () {
print('all done');
},
),
SizedBox(
height: 70,
),
ElevatedButton(
style: ElevatedButton.styleFrom(
primary: Color(0xff16A085),
padding:
EdgeInsets.symmetric(horizontal: 50, vertical: 20),
textStyle:
TextStyle(fontSize: 30, fontWeight: FontWeight.bold)),
onPressed: () {Navigator.push(
context,
MaterialPageRoute(builder: (context) => QuizScreen()),
);},
child: Text(
"Ready now! First question please!",
style: TextStyle(
fontSize: 24,
),
)),
],
),
)
);
}
}
What am I doing wrong? Or is there another simpler way of showing the countdown timer?
CodePudding user response：
You have to write this statement like this
Tween(begin: 120.0, end: 0.0)
instead of it
Tween(begin: 120.0, end: 0)
because any Tween animation accept only double value not int value so modify it then check output
