* Revert "Avoid rebuilding snapshots if no change to source (#11551)"
This reverts commit 74835db563b7c31b4c883eeea15e689a1bdbd303.
This change re-introduces skipping snapshot builds if input sources (and
outputs) have not changed since the last snapshot build, with a bugfix
to include the entry-point source in the checksum used to check whether
rebuild can be skipped. This ensures that the following sequence
invalidates the cached build, resulting in two snapshot builds:
flutter build ios lib/foo.dart
flutter build ios lib/bar.dart
This reverts commit 3d5afb5a81052b7d55661549320d6d43f893f448.
Previously, the snapshot file was recomputed on every build. We now
record checksums for all snapshot inputs (which are catalogued in the
snapshot dependencies file output alongside the snapshot) and only
rebuild if the checksum for any input file has changed.
