at first let me tell you my question.
I want to add an Animation to a Build Widget. When I test both code in a single way it is working fine. If i want to add the Animation to the Build Widget it is not working. I am Flutter beginner but i hope you can help me. I do not found a working way or stackoverflow-page that has a soloution for this problem.
Here is the Code of the Build Widget
@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Colors.white,
appBar: AppBar(
backgroundColor: Colors.white,
title: Text(
"Title",
style: TextStyle(
color: Colors.black,
fontSize: 16,
),
),
leading: IconButton(
icon: Icon(
Icons.arrow_back,
color: Colors.black,
),
onPressed: () {
Navigator.of(context).pop();
},
),
),
body: FutureBuilder(
builder: (context, snapshot) {
if (snapshot.hasData) {
return _buildNews(snapshot.data);
}
if (snapshot.hasError) {
return ErrorView();
}
return Center(
child: SizedBox(
width: 40,
height: 40,
child: CircularProgressIndicator(),
),
);
},
future: Repository.getNews(),
),
);
}
I want to add the following code like appbar. if the icon is pressed, the animation should rotate the entire page.
Widget build(BuildContext context) {
return AnimatedContainer(
transform: Matrix4Transform()
.translate(x: xoffSet, y: yoffSet)
.rotate(angle)
.matrix4,
duration: Duration(milliseconds: 250),
child: Container(
height: MediaQuery.of(context).size.height,
width: MediaQuery.of(context).size.width,
decoration: BoxDecoration(
color: Colors.blue[200],
borderRadius: isOpen
? BorderRadius.circular(10)
: BorderRadius.circular(0)),
child: SafeArea(
child: Stack(
children: [
!isOpen
? IconButton(
icon: Icon(
Icons.menu,
color: Color(0xFF1f186f),
),
onPressed: () {
setState(() {
xoffSet = 150;
yoffSet = 80;
angle = -0.2;
isOpen = true;
});
secondLayerState.setState(() {
secondLayerState.xoffSet = 122;
secondLayerState.yoffSet = 110;
secondLayerState.angle = -0.275;
});
})
: IconButton(
icon: Icon(Icons.arrow_back_ios,
color: Color(0xFF1f186f)),
onPressed: () {
if (isOpen == true) {
setState(() {
xoffSet = 0;
yoffSet = 0;
angle = 0;
isOpen = false;
});
secondLayerState.setState(() {
secondLayerState.xoffSet = 0;
secondLayerState.yoffSet = 0;
secondLayerState.angle = 0;
});
}
}),
Center(
child: Image.asset(
"assets/avatar.png",
height: MediaQuery.of(context).size.height / 2,
),
),
],
),
)));
}
Thank you very much for your help!!!
