Error: 'MapLiteral' isn't a type.

The command
flutter pub global activate l10n
terminates with
Precompiling executables...
Failed to precompile l10n:mkl10n:

Can you please provide your flutter doctor -v?

First I thought this was because I was not on the master channel, butI see the same problem on beta, master and stable.

I see. Since this has to do with a separate package, closing this. You can track this issue at MikeMitterer/dart-l10n-gettext#4
