My first flutter experiment =)
generate with dart run build_runner build
keep dev with dart run build_runner watch
for splash screen:
dart run flutter_native_splash:create
for app icons:
dart run flutter_launcher_icons
get your .keystore file (it's not here, for security reasons)
to check the alias the keystore file uses, run keytool -v -list -keystore platypus.keystore
create the key.properties file inside android folder (there's a sample, quite easy)
to change app name and id: https://stackoverflow.com/a/51550358/22647495
run with flutter buld appbundle
generated app will be at .../build/app/outputs/bundle/release
