Graphql-flutter: Ability to set default Fetch-policy for all query requests

[milind-solutelabs]

I see default fetch policy for Query is FetchPolicy.cacheFirst.

How we can set default fetch-policy for Query requests? I don't want to to change at each Query requests.

This feature doesn't exist but is feasible

How about receiving QueryOptions from below

and expose it as a getter. Then when setting WatchQueryOptions below, get the default values provided from client and apply to _options getter if policy had not been provided in the widget?
