Issue while getting the data from elastic search and bind it to dropdown.Please help!

[chandk87]

I am trying to get the data from elasticsearch and I am trying to bind the same to the dynamic dropdown but I am facing issues. The widgets and data from for loop is not rendering as desired. Can you please help me with this ?

import 'dart:convert'; import 'package:flutter/material.dart'; import './JsonLib/json_schema.dart'; import './ElasticHttpLib/console_http_transport.dart';

class AllFields extends StatefulWidget { AllFields({Key key}) : super(key: key); // This widget is the home page of your application. It is stateful, meaning // that it has a State object (defined below) that contains fields that affect // how it looks.

// This class is the configuration for the state. It holds the values (in this // case the title) provided by the parent (in this case the App widget) and // used by the build method of the State. Fields in a Widget subclass are // always marked "final".

@override _AllFields createState() => new _AllFields(); }

class _AllFields extends State<AllFields> { List data; static List runtime; String form;

Future getResponse() async { final client = Client(ConsoleHttpTransport( Uri.parse(url)));

// bucket aggregation
final rs3 = await client.search(
    '_module', '_doc', null,
    aggregations: {
      'dropdown': {
        'terms': {'field': 'reasonForReporting', 'size': 10}
      }
    }).then((response) {
  setState(() {
    var res = response.aggregations['dropdown'].buckets.toList();

    data = res;
    runtime = data;
  });
}).catchError((e) {
  print(e);
});

}

@override void initState() { getResponse(); super.initState(); }

@override void didChangeDependencies() { getResponse();

super.didChangeDependencies();

}

dynamic response;

@override Widget build(BuildContext context) { // This method is rerun every time setState is called, for instance as done // by the _incrementCounter method above. // // The Flutter framework has been optimized to make rerunning build methods // fast, so that you can just rebuild anything that needs updating rather // than having to individually change instances of widgets. if (runtime != null) { form = json.encode({ 'title': 'Test Form Json Schema', 'description': 'My Description', 'autoValidated': true, 'fields': [ { 'key': 'input1', 'type': 'Input', 'label': 'Hi Group', 'placeholder': "Hi Group flutter", 'value': '', 'required': true }, { 'key': 'password1', 'type': 'Password', 'label': 'Password', 'required': true }, { 'key': 'email1', 'type': 'Email', 'label': 'Email test', 'placeholder': "hola a todos" }, { 'key': 'tareatext1', 'type': 'TareaText', 'label': 'TareaText test', 'placeholder': "hola a todos" }, { 'key': 'radiobutton1', 'type': 'RadioButton', 'label': 'Radio Button tests', 'value': 2, 'items': [ { 'label': "product 1", 'value': 1, }, { 'label': "product 2", 'value': 2, }, { 'label': "product 3", 'value': 3, } ] }, { 'key': 'switch1', 'type': 'Switch', 'label': 'Switch test', 'value': false, }, { 'key': 'checkbox1', 'type': 'Checkbox', 'label': 'Checkbox test', 'items': [ { 'label': "product 1", 'value': true, }, { 'label': "product 2", 'value': false, }, { 'label': "product 3", 'value': false, } ] }, { 'key': 'select1', 'type': 'Select', 'label': 'Select value', 'value': 'product 1', 'items': [ { 'label': "product 1", 'value': "product 1", }, { 'label': "product 2", 'value': "product 2", }, { 'label': "product 3", 'value': "product 3", }, { for (int i = 0; i < runtime.length; i++) { 'label': runtime[i].key.toString(), 'value': runtime[i].key.toString(), } } ] }, ] });
