Problem

I'm trying to save a few CLI arguments into a variable, so it's convenient for me to use later. This works but is quite verbose:

flutter run --dart-define=SENTRY_DSN_CLIENT_KEY=${APP1_SENTRY_DSN_CLIENT_KEY} --dart-define=MAPBOX_ACCESS_TOKEN=${APP1_MAPBOX_ACCESS_TOKEN}

Unfortunately, neither of the following, concise options work. The 2nd --dart-define is not available in the app. I've tried:

flutter run $APP1_DART_DEFINE_FLAGS
flutter run "${APP1_DART_DEFINE_FLAGS[@]}"

How do I workaround an issue which seems to be inside the flutter run tool?

My env file

export APP1_SENTRY_DS=...
export APP1_MAPBOX_ACCESS_TOKEN=...
export APP1_DART_DEFINE_FLAGS="--dart-define=SENTRY_DSN_CLIENT_KEY=${APP1_SENTRY_DSN_CLIENT_KEY} --dart-define=MAPBOX_ACCESS_TOKEN=${APP1_MAPBOX_ACCESS_TOKEN}"

【问题讨论】：

in your env file you define APP1_SENTRY_DS but when defining APP1_DART_DEFINE_FLAGS you reference a different variable APP1_SENTRY_DSN_CLIENT_KEY; I can't tell if you have a typo in the env file, a typo in what you've posted in the question, or if there are more entries in your env file that are not shown here ... ??
nowhere in the question do you show the creation/population of an array so not sure where the reference to SC21281 comes into play here; did you generate the SC2128 and if so could you provide the complete set of code you supplied to shellcheck.net?

Use bash arrays. Properly quote arguments.

APP1_DART_DEFINE_FLAGS=(
   "--dart-define=SENTRY_DSN_CLIENT_KEY=${APP1_SENTRY_DSN_CLIENT_KEY}"
   "--dart-define=MAPBOX_ACCESS_TOKEN=${APP1_MAPBOX_ACCESS_TOKEN}"
)
flutter run "${APP1_DART_DEFINE_FLAGS[@]}"
