Had to install NDK for android

[dragonfax]

To get past the first build error, I had to install the ndk-bundle for android. Otherwise I'd get errors about the lack of the NDK.

~/Library/Android/sdk/tools/bin/sdkmanager "ndk-bundle"

You'll want to document this in your setup docs, as the instructions for setting up and using flutter (including Xcode and Android Studio) don't install the NDK. As its not necessary for regular flutter usage.
