A Hero Animation in one sentence is simply an element of one screen “flying” to the next when the app goes to the next page.
Use the Hero widget to animate a widget from one screen to the next. This recipe uses the following steps:
- Create two screens showing the same image.
- Add a
Herowidget to the first screen. - Add a
Herowidget to the second screen.
And here comes my logic implementation :
Hero(tag:'photo1',child:_circleImage(context,'photo1',"https://auto.ndtvimg.com/car-images/large/ferrari/488-gtb/ferrari-488-gtb.jpg?v=6"),),
Navigator.push(context, MaterialPageRoute(builder: (context)=> Detail(imageUrl,tag))),main.dart
import 'package:flutter/material.dart';
import './ui/home.dart';
void main() => runApp(
MaterialApp(
home: Home(),
)
);home.dart
import 'package:flutter/material.dart';
import 'detail.dart';
class Home extends StatelessWidget {
double rating=0.0;
@override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
appBar: AppBar(
title: Text('home'),
centerTitle: true,
),
body: SafeArea(
child: Column(
mainAxisAlignment: MainAxisAlignment.start,
mainAxisSize: MainAxisSize.max,
children: <Widget>[
Column(
mainAxisSize: MainAxisSize.max,
mainAxisAlignment: MainAxisAlignment.spaceBetween,
children: <Widget>[
Hero(
tag: 'photo1',
child: _circleImage(context,'photo1',"https://auto.ndtvimg.com/car-images/large/ferrari/488-gtb/ferrari-488-gtb.jpg?v=6"),
),
Hero(
tag: 'photo2',
child: _circleImage(context,'photo2',"https://spectatecars.com/wp-content/uploads/2017/10/2019-Ferrari-488-Spider-featured-815x527.jpg"),
),
Hero(
tag: 'photo3',
child: _circleImage(context,'photo3',"https://www.thetruthaboutcars.com/wp-content/uploads/2019/01/2019-mercedes-benz-a-class-sedan-e1547745740100-610x408.jpg"),
)
],
)
],
)),
);
}
Widget _circleImage( BuildContext context, String tag,String imageUrl){
return GestureDetector(
onTap: ()=> Navigator.push(context, MaterialPageRoute(builder: (context)=> Detail(imageUrl,tag))),
child: Container(
width: 120,
height: 120,
decoration: BoxDecoration(
shape: BoxShape.circle,
image: DecorationImage(image: NetworkImage(imageUrl),fit: BoxFit.fill)
),
),
);
}
}
detail.dart
import 'package:flutter/material.dart';
class Detail extends StatelessWidget{
String imageUrl;
String tag;
Detail(this.imageUrl,this.tag);
@override
Widget build(BuildContext context) {
// TODO: implement build

),
),
)
),
);
}
}
