Null safety migration status

This page contains stats for the migration of packages on pub.dev to Dart's sound null safety feature.
The data below is based on the following criteria:
- Package supports null safety: The Dart SDK lower constraint is
>= 2.12.0-0 - Package is unblocked for starting migrating to null safety: All direct dep of the package support null safety
- Blocking score: The number of packages (incl. transitive deps) only blocked from null-safety migration by this package. If a package is blocked by N dependencies, then it only contributes with a blocking score of 1/N.
Note: Pub.dev also has a list of packages with null safety. This may show a slightly lower count than the "raw" counts below, as some categories of packages (e.g. those marked discontinued) are not shown in the pub.dev search UI.
packages with null safety: 306
packages without null safety total: 15135
packages without null safety blocked: 5950
packages without null safety unblocked: 9185
packages in total (w. Dart 2.12 support): 15441
