我尝试使用 FutureBuilder 在 Flutter 中的 ListView 中显示来自 JSON 的结果。但是快照为空,显示无数据信息
Widget getBody() {
return Scaffold(
body: Container(
padding: EdgeInsets.only(left: 16, top: 1, right: 16),
child: FutureBuilder<List<dynamic>>(
future: getprofile(widget.id),
builder: (context, AsyncSnapshot<List<dynamic>> snapshot) {
// String name = snapshot.data['name'];
// print(snapshot);
List<dynamic> data = snapshot.data;
inspect(snapshot);
if (snapshot.hasData) {
return ListView(
children: [
Container(
decoration: BoxDecoration(
gradient: LinearGradient(
begin: Alignment.topCenter,
end: Alignment.bottomCenter,
colors: [Colors.white, Colors.white])),
child: Container(
width: double.infinity,
height: 350.0,
child: Center(
child: Column(
crossAxisAlignment: CrossAxisAlignment.center,
mainAxisAlignment: MainAxisAlignment.center,
@override
void initState() {
getprofile(widget.id);
super.initState();
}
Future<List<dynamic>> getprofile(int id) async {
var response = await Network().getData('/auth/user/$id');
var data = json.decode(response.body)['user'];
return data;
}
如何显示变量?
