We have some TODOs related to ignores in flutter/packages related to making classes const which can now be cleaned up by addressing the TODO (adding const, and removing the ignore). They can be found by searching for:

// TODO(goderbauer): Make this const when this package requires Flutter 3.8 or later.

Any package we make this change in will need to be updated to have a minimum Flutter version of 3.10 (the first stable after 3.8, where the constructors became const).
