Unrated Puzzles

Close #1120
Close #297

Changes

• Adds a switch to the puzzle settings screen to let users play unrated puzzles that don't affect their rating.

add.rated.game.switch.mp4

• Logged out users don't see the rating switch:

logged.out.user.mp4

Testing

Tested using a proxy to spy on what app sends to API.

1. First puzzle is correctly win: false, rated: true

{
	"solutions": [{
		"id": "24pDF",
		"win": false,
		"rated": true
	}]
}

2. Second puzzle is correctly win: true, rated: true

{
	"solutions": [{
		"id": "7nI7d",
		"win": true,
		"rated": true
	}]
}

3. Third puzzle is correctly win: true, rated: false

{
	"solutions": [{
		"id": "6YIPJ",
		"win": false,
		"rated": false
	}]
}

6. Rest of the puzzles are played offline and are correctly rated once I turn the internet back on and the batch is submitted.

{
	"solutions": [{
		"id": "8Cm4H",
		"win": true,
		"rated": false
	}, {
		"id": "0haqU",
		"win": true,
		"rated": true
	}, {
		"id": "5T8Mz",
		"win": true,
		"rated": true
	}, {
		"id": "2106v",
		"win": false,
		"rated": true
	}, {
		"id": "2ZCbv",
		"win": false,
		"rated": false
	}, {
		"id": "9h38Q",
		"win": true,
		"rated": false
	}]
}

Thanks for this!

How does it work with batches? Puzzles work offline too. If you solve puzzle offline, the solution is saved until network is up again. Then batches of puzzle are solved at once.

@veloce Good catch! I updated the testing section above with a video that shows me turning on/off my wifi and turning on/off the rating. I then checked that once the internet was back, the batch puzzle submissions were all correctly rated or not rated. I think this should be ready for a final review

Code looks good.

This feature should be tested. Puzzles are already well tested so it should be relatively easy to add a widget test.

There is already a widget test that solves a puzzle. I guess we should reuse that and intercept the mock storage to verify that the rated flag is correctly saved in database depending on the preferences.

I've rebased your branch to fix the CI @CloudyDino

I approved the code, but the puzzles tests are not OK. Can you have a look? Thanks.

@veloce
Removed the offending line await tester.pumpAndSettle().
Renamed rated to isRatedPreference.
Once this is merged in, I'll base the hints branch off of this for the tests over there

LGTM. Great job, thanks!
