@override
Widget build(BuildContext context) {
return Scaffold(
backgroundColor: Theme.of(context).backgroundColor,
body: Scaffold(
appBar: AppBar(
title: Text("Register"),

body: Container(
child: Center(
child: Column(
children: <Widget>[
Text(

推荐答案
看看您的API，让我认为您正在尝试发布数据.同时，我可以看到您在flutter应用程序中使用的是get请求.
Taking a look at your API makes me think that you are trying to post data. At the same time, I can see that you are using a get request in your flutter app.
如果您要发布数据，请从flutter应用发出POST请求，而不是GET请求.
If you are trying to post data then make a POST request from your flutter app rather then a GET request.
以下是使用 HTTP 包的扑朔迷离的POST请求示例.
Here's an example of POST request in flutter using the HTTP package.
示例POST请求:
String url = "https://www.ekspar.com.tr/onarim/post.php";
var response = await http.post(url, body: {
"adi":"YOUR_DATA",
"soyadi":"YOUR_DATA"
});
var body = jsonDecode(response.body);
if(response.statusCode == 200){
debugPrint("Data posted successfully");
}else{
debugPrint("Something went wrong! Status Code is: ${response.statusCode}");
}
