Dart Twitter API

A Project that was made to make using the Twitter API from flutter and dart a bit easier.

This package contains a high level functionality for connecting to the Twitter API. Provice the secret and public keys, and then make the request to Twitter. The package will handle all of the authentication. This only works for application authentication. User authentication is not implemented and is not planned for the future.

How to Use

Below is an example of how the package would be used.

import 'package:twitter_api/twitter_api.dart';

// Creating the twitterApi Object with the secret and public keys
// These keys are generated from the twitter developer page
// Dont share the keys with anyone
final _twitterOauth = new twitterApi(
  consumerKey: consumerApiKey,
  consumerSecret: consumerApiSecret,
  token: accessToken,
  tokenSecret: accessTokenSecret
);

// Make the request to twitter
Future twitterRequest = _twitterOauth.getTwitterRequest(
  // Http Method
  "GET", 
  // Endpoint you are trying to reach
  "statuses/user_timeline.json", 
  // The options for the request
  options: {
    "user_id": "19025957",
    "screen_name": "TTCnotices",
    "count": "20",
    "trim_user": "true",
    "tweet_mode": "extended", // Used to prevent truncating tweets
  },
);

// Wait for the future to finish
var res = await twitterRequest;

// Print off the response
print(res.statusCode); 
print(res.body);

Requests

Only application authentication is supported by this package.

There are two different types of paramters that will be needed. Depoendant and Independant

The first type is the independant paramters. These are things that every single request will need, no matter the content you are trying to get. These values include:

• A consumer API key
• A consumer API secret key
• An access token
• A secret access token

These are the keys that are used to authenticate your request. Make sure they are correctly entered. You should keep these secret and private.

Next are the dependant variables. These are things that depend on the type of request you are trying to make. These values include:

• method: HTTP Method
  • This is a required parameter of type String
  • GET or POST
• url: The endpoint you are trying to reach
  • This is a required paramter of type String
  • Some examples on the twitter website include /1.1/ but do not include that when making requests here. That part is already added internally
• options: The parameters of the request you are trying to make
  • This is an optional paramter of type Map<String, String>
  • These are things like which user you are trying to view, how many tweets you are trying to get, whether to strip user info from the response or not
  • The full list of these parameters can be found at the Twitter Developer Website

Response

Below is a truncated example of the data that is returned from the above example. It is initially sent as a string and needs to be parsed to get to this state.

To convert it from a string to a List of Maps:

import 'dart:convert';
var tweets = json.decode(res.body);

The data that comes out of the request after converting it:

var resBody = [
