Introduction

The OmniIndex dart package is a library which handles commnication between OmniIndex clients and their relating data within a flutter/dart application environment.

Getting started

Installation

Using this package as a library

Set up your dependency;

With Dart:

dart pub add omniindex

With Flutter:

flutter add omniindex

This will add a line like this to your package's pubspec.yaml (and run an implicit dart pub get):

dependencies:
  omniindex:^1.0.0

Alternatively, your editor might support dart pub get or flutter pub get. Check the docs for your editor to learn more.

Now in your Dart code, you can import and use the package:

import 'package:omniindex/omniindex.dart';

Usage

1. Create your constructor by providing details from an environment variable file or other secure source. Never hard code these values

   * @param String apiServer (server address)
   * @param String seedNode (seeed)
   * @param String nodeServer (node server)
   * @param String localDomain (company domain)
   

2. Once you have these parameters you can include the omniindex package in your flutter/dart project:

   import 'package:omniindex/omniindex.dart';
   

3. Next, use the constructor details to create an connected instance of omniindex (oidx) and act on it.

   Example:

   // Instantiate the default
   OmniIndex oidx = OmniIndex(debug: true);
   

   Sample:

   
   /// fetchInfo function takes in paramters [select] and [from] along with a Map<String, String>[details]
   /// to act on.
   Future<dynamic> fetchInfo(String select, String from, Map<String, String> details) async {
       dynamic jResponse = [];
   
       String query = "SELECT $select FROM .$from;";
   
       String body = jsonEncode(<String, dynamic>{
       "showEmptyFields": "false",
       "analyticQuery": query,
       //"showProtected": "true",
       "user": details["uid"],
       "unitName": details["email"]
       });
   
       // accept the default constructor. values are established via a configuration json file
       // see the README.md
       OmniIndex oidx = OmniIndex();
       String response = await oidx.callOmni('runanalyticqueryml', body, user);
   
       jResponse = jsonDecode(response);
       List<dynamic> res = jResponse['results'];
   
       return ((res.length == 0) ? 0 : ((select != '*') ? res.last[select] : jResponse['results']));
   }
   
   
   // set up our details
   Map<String, String> details;
   details['email'] = '[e-mail]';
   details['uid'] = 's123456789Id';
      
   // fetch the height data and store in our details Map
   await fetchInfo('height', 'profile where height != 0',  details).then((height) => details['height'] = height);
   
   // validate / act on height from details['height']
      
   - set your APICredentials accordingly
   
   If you don't have these values see [Pre-requisites above](#pre-requisite)
   you must have a valid OmniIndex API license/key to use this package
