Retrieving Json Response Data With Dynamic Key

let data = [  {    "assetCategory": {       "canCreate": false,       "canView": false,       "canUpdate": false,       "canDelete": false,       "isMenu": false,       "parent": "settings"     }  }]

let unknownNames = data.map( item => Object.keys(item)) // returns ['assetCategory']//Returns array of all the unknown namesconsole.log(unknownNames);

get value from json with dynamic key

var t={'color':'red'}; // dynamic json data.
for(n in t)
{
    alert(n);// n = key
    var val =t[n];// value where key is n

}

Getting values from nested JSON with a dynamic key in a database

If you want one row per nested item, you can use json_each()

select b.id, 
       t.uid, 
       t.item ->> 'path' as path,
       t.item ->> '__id' as item_id, 
       t.item ->> 'state' as state
from bp_instances b
  cross join json_each(body -> '__tasks') as t(uid, item)
WHERE body ->> '__templateId' = '6666f537-a370-4ebd-b709-ccb1d04b2da3' 

Based on your sample data this returns:

id | uid                                  | path                                        | item_id                              | state

JSON Get the name of dynamically changing key with PHP

Can you provide a couple more examples?
Or try this code and let us know if it breaks

<?php

$json='{
"_text": "this is a test",
"entities": {
    "dynamic_key": [
        {
            "confidence": 0.99,
            "value": "thi is the answer"
        }
    ]
},
"msg_id": "1234532123"
}';


$data=json_decode($json,true);

foreach ($data['entities'] as $key=>$val)
{
echo "VALUE IS $key\n values are ";
var_dump($val);


}

flutter problem in json parsing of dynamic key values

Just check out the example that I have made for you based on the json that you provided.

import 'dart:convert';

import 'package:flutter/material.dart';
import 'package:json_parsing_example/models.dart';
import 'package:http/http.dart' as http;

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(home: HomePage());
  }
}

class HomePage extends StatefulWidget {
  @override
  _HomePageState createState() => _HomePageState();
}

class _HomePageState extends State<HomePage> {
  double value;

  String json = '''
  {
    "success": true,
    "data": {
        "ones": [{
                "id": "2",
                "username": "LM10002"
            },
            {
                "id": "6",
                "username": "LM10006"
            }
        ],
        "twos": [{
                "id": "3",
                "username": "LM10003"
            },
            {
                "id": "8",
                "username": "LM10008"
            }
        ],
        "threes": [{
            "id": "4",
            "username": "LM10004"
        }],
        "fours": [{
                "id": "5",
                "username": "LM10005"
            },
            {
                "id": "14",
                "username": "GT10014"
            }
        ]
    }
}
  
  ''';
  @override
  void initState() {
    super.initState();

    getData();
  }

  getData() {
    Map mapValue = jsonDecode(json);
    // This is where you iterate via the data object
    // that is the value which is key,value pair
    List<Data> data = List();
    mapValue['data'].forEach((key, value) {
      List<User> user = List();
      value.forEach((item) {
        user.add(User(id: item['id'], username: item['username']));
      });
      data.add(Data(name: key, userList: user));
    });

    data.forEach((element) {
      print(element.name + " : " + '${element.userList.length}');
    });
  }

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      body: Container(child: Text('s')),
    );
  }
}

class Data {
  final String name;
  final List<User> userList;

  Data({this.name, this.userList});
}

class User {
  final String id;
  final String username;

  User({this.id, this.username});
}

Let me know if it works.
