Commit 7f0af11cee (support/testing/tests/package/test_flutter.py: new
runtime test) added a simple test that just checked that the systemd
unit launching the application, was active.
It is perfectly possible, from a systemd perspective, that the unit is
active, while the application actually crashes.
Instead, what we need to check, is that the application does actually
render "something"; we don't really care what, as long as we know it is
actually rendering, thus the graphical stack is working and the
aplication stack is running.
Extend the flutter runtime test to also check that the framebuffer is
modified by the application when it is running, similarly to what we do
in the weston test.
We drop the activation of the unit and start it manually, as we want to
check the state of the CRC before, while, and after the application
runs.
We also need to disable the blinking cursor on the console, or we would
not be able to detect whether a change in CRC is due to the application
starting rendering, or to the cursor blinking. We tell the kernel to
disable the cursor with the appropriate kernel command line parameter.
