我是 flutter 的新手,但我做了很多工作来学习我的项目所需的一切。
我有一个由服务器使用 HTTP 发送的 JSON:
[{"equipe1":"PSG","equipe2":"DIJON","type_prono":"1N2"},{"equipe1":"MONACO","equipe2":"REIMS","type_prono":"1N2"},{"equipe1":"TOULOUSE","equipe2":"RENNES","type_prono":"1N2"},{"equipe1":"MONTPELLIER","equipe2":"STRASBOURG","type_prono":"1N2"},{"equipe1":"AMIENS","equipe2":"METZ","type_prono":"1N2"},{"equipe1":"BREST","equipe2":"ANGERS","type_prono":"1N2"},{"equipe1":"LORIENT","equipe2":"CHAMBLY","type_prono":"1N2"}]
我尝试将其设置为数据表小部件,但似乎做起来很复杂。
现在这是我的整个代码:
import 'package:flutter/material.dart';
import 'dart:convert';
import 'package:http/http.dart' as http;
import 'dart:async';
// Create a Form widget.
class Affiche_grille extends StatefulWidget {
@override
Affiche_grille_State createState() {
return Affiche_grille_State();
}
}
// Create a corresponding State class.
// This class holds data related to the form.
class Affiche_grille_State extends State<Affiche_grille> {
@override
final _formKey = GlobalKey<FormState>();
Grille_display() async {
// SERVER LOGIN API URL
var url = 'http://www.axis-medias.fr/game_app/display_grid.php';
// Store all data with Param Name.
var data = {'id_grille': 1};
// Starting Web API Call.
var response = await http.post(url, body: json.encode(data));
// Getting Server response into variable.
var match = json.decode(response.body);
}
Widget build(BuildContext context) {
// Build a Form widget using the _formKey created above.
var listmatch = Grille_display();
return Form(
key: _formKey,
child: Column(
crossAxisAlignment: CrossAxisAlignment.start,
children: <Widget>[
DataTable(
columnSpacing: 20,
columns: [
DataColumn(
label: Text("Eq 1"),
numeric: false,
tooltip: "",
),
DataColumn(
label: Text("Eq 2"),
numeric: false,
tooltip: "",
),
DataColumn(
label: Text("Type pro"),
numeric: false,
tooltip: "",
),
],
rows: EquipeList.map((equipe_detail) => DataRow(
cells: [
DataCell(
Text(equipe_detail['equipe1'].toString()),
),
DataCell(
Text(equipe_detail['equipe2'].toString()),
),
DataCell(
Text(equipe_detail['type_prono'].toString()),
),
]),
).toList(),
)
],
)
);
}
}
class Match_detail {
String equipe1;
String equipe2;
String typeProno;
Match_detail({this.equipe1, this.equipe2, this.typeProno});
Match_detail.fromJson(Map<String, dynamic> json) {
equipe1 = json['equipe1'];
equipe2 = json['equipe2'];
typeProno = json['type_prono'];
}
Map<String, dynamic> toJson() {
final Map<String, dynamic> data = new Map<String, dynamic>();
data['equipe1'] = this.equipe1;
data['equipe2'] = this.equipe2;
data['type_prono'] = this.typeProno;
return data;
}
}
class EquipeList {
List<Match_detail> breeds;
EquipeList({this.breeds});
factory EquipeList.fromJson(List<dynamic> json) {
return EquipeList(
breeds: json
.map((e) => Match_detail.fromJson(e as Map<String, dynamic>))
.toList());
}
}
它不起作用:(它告诉我:错误:没有为类“EquipeList”定义方法“map”。([flutter_app] lib中的undefined_method
