Usage

• Import the package

dependencies:
  splitwise_api: ^2.0.1

• Import in the file

import 'package:splitwise_api/splitwise_api.dart';

• Setup SharedPreferences or any other system to save the token and tokenSecret to keep user logged in.
  • For Example :-

import 'package:shared_preferences/shared_preferences.dart';

class SplitWiseHelper {
  saveTokens(TokensHelper tokens) async {
    final prefs = await SharedPreferences.getInstance();
    prefs.setStringList('tokens',[tokens.token,tokens.tokenSecret]);
  }

  getTokens() async {
    final prefs = await SharedPreferences.getInstance();
   return prefs.getString('tokens');
  }
}

• Now Use the Wrapper and save the tokens.
  • ForExample :-

import 'package:splitwise_api/splitwise_api.dart';
import 'package:splitwise_api/src/util/data/model/current_user_entity.dart';


void main() async {
  SplitWiseService splitWiseService =
  SplitWiseService.initialize(_consumerKey, _consumerSecret);

  /// SplitWiseHelper is for saving and retrieving from shared storage
  SplitWiseHelper splitWiseHelper = SplitWiseHelper();
  if (splitWiseHelper.getTokens() == null) {
    var authURL = splitWiseService.validateClient();
    print(authURL);
    //This Will print the token and also return them save them to Shared Prefs
    TokensHelper tokens = await splitWiseService.validateClient(
        verifier: 'theTokenYouGetAfterAuthorization');
    await splitWiseHelper.saveTokens(tokens);

    splitWiseService.validateClient(tokens: tokens);
  } else {
    splitWiseService.validateClient(
        tokens: /* tokens from saved */);
    //Example
    CurrentUserEntity currentUserEntity = await splitWiseService
        .getCurrentUser();
    print(currentUserEntity.user.firstName);
  }
}
