With version 3.0.2 `name` of the file_picker library becomes
non-nullable, so a warning was issued for users who had already
used version 3.0.2, as we still assumed that `name` is nullable.
Increasing the version and removing the exclamation mark removes
the warning.

Development on the quiver_* subpackages has been discontinued in favour
of the main quiver package at https://github.com/google/quiver-dart. The
code itself is identical, but is more actively maintained.
Updated the dependency on the tuple package to 2.0.0, since it also
depends on quiver 3.0.0. Both packages has been migrated to null-safety
at those versions.
