can't set state to list
I am creating a quiz app. In the app I have symbols (emojis) that per default are a blue dot (kept in a List emojis[]). If the user answers correct, the emoji turns green, and for wrong answer the emoji turns red. To test this I made a very simple app and everything worked as it should. But

Navigator problem
I have a three page app, the 1st page displays a list of recipes, the second page displays a recipe from the first page, and the third page creates new recipes. After a recipe is created I push to the display page for the new recipe. The only navigation button are the back button and the AppBar

Any tool to quickly resize mobile app?
Hi folks When developing my mobile application I have to create and fire up a new emulator just to test with different resolutions. This is really tedious and time consuming!Is there a tool out there or any way to have a ‘free aspect’ window (like a web browser when developing a website for example) that you can resize and see the app resizing in real time?

I miss coverage data in Android Studio - what gives?
No matter what I seem to try, I can't display coverage data in Android Studio. There seems to be no option to run Flutter tests for a whole directory (test) and collect coverage.Per-test coverage collection is ran with dart command instead of going through flutter shell, so they fail, can't run.When running flutter test --coverage from command line, I get lcov.info in coverage directory. One of two things happen:Choose coverage suite to display ui doesn't pick it up and can't manually add it either for whatever reasonIf it does pick it up and can select it, Android Studio displays coverage data as though there were no lines covered whatsoeverIn my opinion, this seems such basic thing nowadays that I'm suprised I find myself on reddit asking people for advice and giving a shout out to the dev team to look into this.In an ideal world:I hit (re-)run tests with coverageAndroid Studio knows it's a Flutter projectRuns flutter testsBeing pretty and all that, gives me color coded feedback in code files what I missedQ: am I missing something (I can't put it past me that I do)?​Currently useing Flutter 1.5.4 with Android studio 3.4.edit: formatting
