If your functions are declared async, you need to use the await keyword when calling them. And consequently you need to declare the Cloud Function itself as async.

So the following should do the trick:

You should use the FutureBuilder widget to update your user interface when the data is available. The code you provided attempts to build the widgets before the data is received. This causes the _historyList to still be null.

heres is the hook

As per comment on issue 36065, when a .NET Core 3.1 worker service runs as a windows service "Directory.GetCurrentDirectory() will point to %WINDIR%\system32". Therefore to get the current directory, you could use some reflection and something like:

parent.scrollTop is what you need.

In case of problems with valgrind, it is always recommended to try with a recent version, either the last release or the git version.

Note that it is quite easy to recompile valgrind from sources, at it has very few dependencies.

In case of specific problems with stack traces, it is always useful to compare the stack traces produced by valgrind and gdb by using valgrind + gdb + vgdb.

Put a breakpoint in gdb at relevant places, and you can then compare the gdb stacktrace produced by the gdb backtrace command and the valgrind stacktrace produced by the monitoring command:

Do these things

1. add org.gradle.caching=true add org.gradle.daemon=true If you have two variants of your app in the dev variant disable pngcrunching and disable it such that instead of searching for appropriate image it searches for a particular image itself(xxhdpi)

in your dev block in gradle add these two lines splits.abi.enable=false and splits.density.enable=false

Optimize your firebase crashalytics if you're using it. [Also see the google talk on improving Gradle builds][1]

I improved my gradle time from 17 minutes to 9 following the above practices. Make sure you have offlinegradle button clicked in the gradle tab to the right of the screen. [1]: https://www.youtube.com/watch?v=7ll-rkLCtyk

You just have another instance of Mosquitto already running.

Use ps ax | grep mosq to see if Mosquitto is still running outside of a container. If you find it, use sudo kill -9 PID where you replace PID with its process ID. Or you can try sudo killall -9 mosquitto.

If that doesn't solve the problem, check Docker.

Use docker ps to list all the Docker containers currently running.

Use docker stop ID where you replace the ID for each container that's running.

If you fail to find an instance of Mosquitto, reboot your computer and try again.
