alternative to future builder code example
Example 1: flutter future builder
FutureBuilder<String>(
future: _fetchNetworkCall, // async work
builder: (BuildContext context, AsyncSnapshot<String> snapshot) {
switch (snapshot.connectionState) {
case ConnectionState.waiting: return Text('Loading....');
default:
if (snapshot.hasError)
return Text('Error: ${snapshot.error}');
else
return Text('Result: ${snapshot.data}');
}
},
),
Example 2: future builder snapshot list
FutureBuilder(
future: _fetchListItems(),
builder: (context, AsyncSnapshot snapshot) {
if (!snapshot.hasData) {
return Center(child: CircularProgressIndicator());
} else {
Container(
child: ListView.builder(
itemCount: snapshot.data.length,
scrollDirection: Axis.horizontal,
itemBuilder: (BuildContext context, int index) {
return Text('${snapshot.data[index].title}');
}));
}
});
