Keypair.fromSeckeySync constructor

Keypair.fromSeckeySync(Uint8List seckey, { bool skipValidation = false, })

Creates a Keypair from a seckey byte array.

This method should only be used to recreate a keypair from a previously generated seckey. Generating keypairs from a random seed should be done with the Keypair.fromSeedSync method.

Throws a exception for invalid seckeys that do not pass validation. Creates a Keypair from a seckey byte array.

This method should only be used to recreate a keypair from a previously generated seckey. Generating keypairs from a random seed should be done with the Keypair.fromSeedSync method.

Throws a exception for invalid seckeys that do not pass validation.
