    --dart-define=<foo=bar>                                  Additional key-value pairs that will be available as constants from
                                                             the String.fromEnvironment, bool.fromEnvironment, and

                                                             Multiple defines can be passed by repeating "--dart-define" multiple
                                                             times.
    --dart-define-from-file=<use-define-config.json|.env>    The path of a .json or .env file containing key-value pairs that
                                                             will be available as environment variables.
                                                             These can be accessed using the String.fromEnvironment,
                                                             bool.fromEnvironment, and int.fromEnvironment constructors.
                                                             Multiple defines can be passed by repeating
                                                             "--dart-define-from-file" multiple times.

                                                             over entries from these files.
-t, --target=<path>                                          The main entry-point file of the application, as run on the device.
                                                             If the "--target" option is omitted, but a file name is provided on
                                                             the command line, then that is used instead.
                                                             (defaults to "lib/main.dart")

Target options
    --arch=<target arch>                                     The target architecture to build for.

          [arm] (default)                                    Build for 32-bit ARM. (armv7-linux-gnueabihf)
          [arm64]                                            Build for 64-bit ARM. (aarch64-linux-gnu)
          [x64]                                              Build for x86-64. (x86_64-linux-gnu)

    --cpu=<target cpu>                                       If specified, uses an engine tuned for the given CPU. An engine
                                                             tuned for one CPU will likely not work on other CPUs.

          [generic] (default)                                Don't use a tuned engine. The generic engine will work on all CPUs
                                                             of the specified architecture.
          [pi3]                                              Use a Raspberry Pi 3 tuned engine. Compatible with arm and arm64.
                                                             (-mcpu=cortex-a53+nocrypto -mtune=cortex-a53)
          [pi4]                                              Use a Raspberry Pi 4 tuned engine. Compatible with arm and arm64.
                                                             (-mcpu=cortex-a72+nocrypto -mtune=cortex-a72)
