flutter's build modes
the flutter tooling supports three modes when compiling your app,
and a headless mode for testing.
you choose a compilation mode depending on where you are in
the development cycle. are you debugging your code? do you
need profiling information? are you ready to deploy your app?
a quick summary for when to use which mode is as follows:
the rest of the page details these modes.

debug
in debug mode, the app is set up for debugging on the physical
device, emulator, or simulator.
debug mode for mobile apps mean that:
debug mode for a web app means that:
by default, flutter run compiles to debug mode.
your IDE supports this mode. android studio,
for example, provides a run > debug… menu option,
as well as a green bug icon overlaid with a small triangle
on the project page.

release
use release mode for deploying the app, when you want maximum
optimization and minimal footprint size. for mobile, release mode
(which is not supported on the simulator or emulator), means that:
release mode for a web app means that:
the command flutter run --release compiles to release mode.
your IDE supports this mode. android studio, for example,
provides a run > run… menu option, as well as a triangular
green run button icon on the project page.
you can compile to release mode for a specific target
with flutter build <target>. for a list of supported targets,
use flutter help build.
