building-games-with-flutter's Issues

I've updated the flame-engine version in sample app

My thanks to Paul Teale for the great unique book about the flame-engine.
I post this thread just in case if anybody is curious about sample code migration to the latest version of the flame packages.
You can find the flame v1.8.0 migration steps in this repository: https://github.com/tnsoftbear/migrate_building_games_with_flutter_book_app
Feel free to post PR and issues there, if you see necessary fixes that can be applied more.

and using
addHitbox(HitboxRectangle()); -> add(RectangleHitbox());
but I don't know how can change
renderHitboxes(canvas, paint: squarePaint);
into lame 1.5.0 and got an error

Flame package version...

I wonder if you have any plans to update the Flame package version applied to this repo to the latest version(1.6.0).
If you have a plan, when will you update it?
There is a big difference between the Flame 1.0.0 version and the current version,
and I think it is better to study the latest version as much as possible for the future.
