Answer 1

Try to change
$client->setScopes([\Google_Service_Sheets::spreadsheets]);
To. I find this way works better.
$client->setScopes(['https://www.googleapis.com/auth/spreadsheets']);
The way you are doing it should work but you need to have the correct case
$client->setScopes(Google_Service_Sheets::SPREADSHEETS);

Answer 2

Update this code:
$client->setScopes(\Google_Service_Sheets::SPREADSHEETS);
$service = new Google_Service_Sheets($client);
to this:
$client->setScopes(Google\Service\Sheets::SPREADSHEETS);
$service = new Google\Service\Sheets($client);
