super.initState();
dbHelper = DbHelper();
}
#override
Widget build(BuildContext context) {
return Scaffold (
appBar: AppBar(
title: Text("News Application"),
centerTitle: true,
backgroundColor: Colors.black,
titleTextStyle: TextStyle(color: Colors.white),
),
body: FutureBuilder (
future: Future.wait([getEverything(),dbHelper.getAllNews()]),
builder: (BuildContext context, AsyncSnapshot<List<dynamic>> snapshot) {
if(snapshot.hasError) {
// So basically here if there is an error , i woul like to show data from database
// i tried to get data from snapshot like this : snapshot.data[0]...and snapshot.data[1]
// but no data is returned..
return new Center(
child: new CircularProgressIndicator(
backgroundColor: Colors.black,
),
);
} else {
if(snapshot.connectionState == ConnectionState.done){
return new Container(
color: Colors.black,
child: GridView.count(
padding: const EdgeInsets.all(20),
crossAxisCount: 2,
children: List.generate(snapshot.data.articles.length, (index) {
return new GestureDetector(
onTap: (){
Navigator.push(
context,
MaterialPageRoute(builder: (context) => DetailsScreen(
image: snapshot.data.articles[index].urlToImage,
author: snapshot.data.articles[index].author,
title: snapshot.data.articles[index].title,
description: snapshot.data.articles[index].description,
publishedAt: snapshot.data.articles[index].publishedAt,
content: snapshot.data.articles[index].content,
))
);
},
child: Card(
elevation: 12,
child: new Column(
children: [
Image.network(snapshot.data.articles[index].urlToImage,
width: 250,),
Text(snapshot.data.articles[index].description)
],
),
),
);
}
)));
}
}
return new Center(
child: Visibility(
visible: true,
child: CircularProgressIndicator(
backgroundColor: Colors.black,
),
),
);
},
),
);
}
