retrieve all rows in Google Spreadsheet via API using Laravel

I'm trying to get the data from Google spread sheet by using this library: https://github.com/kawax/laravel-google-sheets, and I follow this tutorial to configure the setup of API and no any error, but once I tried to implement any of the examples they provide in the above link, it show me some errors:

Example 1 (on their link):

Undefined variable: request

Example 2 (on their link):

Unresolvable dependency resolving [Parameter #0 [ array $config ]] in class PulkitJalan\Google\Client

Can anyone guide me through the solution how I can get the data from spreadsheet or solve the problem considered here.
