I was trying to upgrade my project to some of the latest versions, I'm unable to get to null-safety since some of the dependencies in the project haven't been updated.
I've resorted to sdk version 2.10, along with that I updated all core packages with resolved all the breaking changes. Some of the deprecated changes (i.e FlatButton to TextButton, hasn't been resolved yet).
I ran into a couple problems building the solution, and after consulting some old Stack posts I've cobbled together gradle file updates, upgrade to Android Studio etc...
However, I'm receiving warnings when I build the solution as uses or overrides a deprecated API and when it installs on the virtual device it fails launch without providing an error.
I'm wondering whether my hacks on the gradle files are the cause - I wanted to get a confirmation whether these gradle updates are correct (specifically the versions that are in use).
