Thanks for the report. Have you tried running flutter upgrade ?

[TheAlphamerc]

no

[esDotDev]

I'd recommend you try upgrading to the latest versions of Flutter, we haven't tested in in 1.9 which is quite old now. In your terminal in your IDE, just enter flutter upgrade, you also might want to throw in a flutter clean for good measure,

[dcocom]

Can you try following the next steps?:

• Remove the /Android folder
• Run flutter create . (don't forget the dot at the end)
• Run flutter run as usual

Your output mention some incompatibilities. I would also recommend checking your flutter doctor your Android NDK is not setup (not required but good to have) and you haven't accepted some licensing.

@TheAlphamerc I also suggest you try out the suggestions by @esDotDev and @dcocom. The parallax_travel_cards_hero project was able to run on my computer without any issues
