Initiate an instance of PayPay

Uses the client ID and client secret to fetch an access token. init() Must be called before any other function. Tokens expire so this function has to be called again before expirations to avoid errors when performing API calls.

PayPal payPal = PayPal(
  clientID: appKey, 
  clientSecret: appSecret,
  sandboxMode: false,//Sandbox mode false to go live. Perform real transactions
);
PayPalAccessToken payPalAccessToken = await payPal.init();
print(payPalAccessToken.access_token);
