Master builds are broken

Currently master is compiling but not running for me:

TBI which commit introduced the regression, this issue clearly shows we need CI integration.

I investigated this a bit. It seams that the apk doesn't include the flutter.so file in the /lib directory for all platforms. This caused an error for release builds as well, and forced me to insert ndk { abiFilters 'armeabi-v7a' } under defaultConfig in the app/build.gradle.

Can you please run flutter build apk and then flutter install to see what happens on your device (better test it on a 64bit device)?

You can then also drag the apk file to Android studio and try to analyse it there.

Searching for the error on Google shows that it might be a multidex issue as well.

Please be sure to run flutter clean. I wasted a two hours on it today because I forgot to do it.

I tried adding multidex as first step but this didn't resolve the issue.

Please be sure to run flutter clean. I wasted a two hours on it today because I forgot to do it.
