What kind of app performance can I expect?

You can expect excellent performance. Flutter is
designed to help developers easily achieve a constant 60fps.
Flutter apps run via natively compiled code—no
interpreters are involved.
This means that Flutter apps start quickly.

What kind of developer cycles can I expect? How long between edit and refresh?

Flutter implements a hot reload developer cycle. You can expect
sub-second reload times, on a device or an emulator/simulator.

Flutter’s hot reload is stateful, which means the app state
is retained after a reload. This means you can quickly iterate
on a screen deeply nested in your app, without starting
from the home screen after every reload.

How is hot reload different from hot restart?
