Why it shows this?
Resolving dependencies...
Because walletappui depends on flutter_barcode_scanner ^3.6.2 which doesn't match any versions, version solving failed.
exit code 1

[@Deivamani003]

you can use flutter_barcode_scanner: ^2.0.0 this version it will work

Guys, I am facing an issue only on this tutorial example. It says "Hot reload was rejected:
Error while starting Kernel isolate task.
Try performing a hot restart instead."
Hot restart gives back "Could not prepare isolate" and "Could not create root isolate" and doesn't work, as well.
