Do we know how Meltan evolves into Melmetal in Sword and Shield?

Question

Currently the only way to evolve Meltan is through Pokemon Go with 400 candies.

Bumping this up as Pokemon Home has released

Answer 1

Thank you to Boaty McBoatface for bringing this back to attention.

You can't.

You have to bring in an already-evolved Melmetal.

Welp, guess we gotta wait until G-Max Melmetal comes out

Answer 2

There is no way to obtain Meltan in-game in SwSh, so the only way to obtain it or Melmetal is through Pokemon HOME; transferring from LGPE (or Go if that is possible but probably not) once HOME is released. Therefore, we do not know (unless someone has hacked in a Meltan).
