its not an HM anymore you have to find it.
In Pokemon Platinum, Flash is a TM.
all the Pokemon on dimmond that can learn flash can still learn flash in the platinum game too
go to floor 3 of Veilstone department store =)

You shall have it when you defeat the 7th gym leader

how do you use flash? just go to pokemon and go to the pokemon that knows flash. press A and it will say in blue text "Flash" select that and it will use Flash. it's very useful in dark caves.
buy the Pokemon platinum book
The 151st Pokemon is Mew and is unobtainable in Pokemon Platinum.
