由于代码如此庞大且超过 1000 行，我无法放置完整代码，我可以放置一些信息代码，在其中调用函数并从服务器获取数据，我想将这些数据显示在 home 的正文中，我已经为 homebody 创建了一个单独的文件并在主页中调用它。但我无法在正文功能中传递服务器数据，谁能帮帮我，我是一个初学者
class HomePage extends StatefulWidget {
const HomePage({Key? key}) : super(key: key);
@override
_HomePageState createState() => _HomePageState();
}
class _HomePageState extends State<HomePage> {
bool isLoggedIn = false;
String schoolid = "";
String uid = "";
String pwd = "";
NetworkHandler networkHandler = NetworkHandler();
ProfileModel profileModel = ProfileModel();
DateTime? backbuttonpressedtime;
_HomePageState() {
MySharedPreferences.instance
.getBooleanValue("loggedin")
.then((value) => setState(() {
stringer.isLoggedIn1101 = value;
}));
MySharedPreferences.instance
.getStringValue("schoolcode")
.then((value) => setState(() {
stringer.schoolid1101 = value;
}));
MySharedPreferences.instance
.getStringValue("uid")
.then((value) => setState(() {
stringer.uid1101 = value;
}));
MySharedPreferences.instance
.getStringValue("password")
.then((value) => setState(() {
stringer.pwd1101 = value;
}));
MySharedPreferences.instance
.getStringValue("image")
.then((value) => setState(() {
stringer.img1101 = value;
}));
Map<String, String> dataprofile = {
"schoolid": stringer.schoolid1101,
"studid": stringer.uid1101,
"password": stringer.pwd1101,
"image": stringer.img1101,
};
usrprofile(dataprofile);
}
@override
Widget build(BuildContext context) {
// TODO: implement build
return Scaffold(
appBar: AppBar(
title: const Text("Home"),
backgroundColor: Vx.blue900,
iconTheme: const IconThemeData(color: Colors.white)),
drawer: MyDrawer(),
body:
child: profile(context),
),
);
}
Future<void> usrprofile(Map<String, String> data) async {
Map<String, String> usrdata = {
"schoolid": stringer.schoolid1101,
"studid": stringer.uid1101,
"password": stringer.pwd1101,
};
try {
var response = await networkHandler
.post("Api.php?apicall=profile", data)
.then((value) => value.body);
Map<String, dynamic> map = jsonDecode(response);
// print(map);
// return;
if (map["error"] == true) {
Fluttertoast.showToast(
msg: map["message"],
// msg: "Your Device may facing some Connectivity issue...",
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1);
return;
} else {
// print(map["user"]);
Fluttertoast.showToast(
msg: "Wait we are fatching information...",
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1);
ProfileModel profileModel = ProfileModel.fromJson(map["user"]);
}
} catch (e) {
Fluttertoast.showToast(
msg: e.toString(),
toastLength: Toast.LENGTH_SHORT,
gravity: ToastGravity.CENTER,
timeInSecForIosWeb: 1);
}
}
}
在这里，我想在另一个名为的文件中准备的函数中传递数据
profile(context)
import 'dart:convert';
import 'dart:typed_data';
import 'package:flutter/material.dart';
import 'package:school_book/utils/strings.dart';
Widget profile(context) => Builder(builder: (context) {
final Map item;
Uint8List profile = base64.decode(img1101);
