DVDatabaseAuthProvider class

Accounts in a dv_accounts table: an id, the address, a name and a salted PBKDF2 hash of the password. The password itself is never stored.

One address is one account. The address is kept trimmed and in lower case, and the table's unique key decides between two sign-ups for the same address at once, so two web processes over one database cannot both create it.

Methods

anyAccount() → Future<bool>

Whether this application has any account at all, which is what makes a start a first run.

override

changeEmail(String id, String email) → Future<AuthUser>

Moves the account with id to email. Throws AuthException with AuthFailure.accountExists when another account has that address and AuthFailure.invalidEmail when it is not one.

override

changePassword(String id, String password) → Future<void>

Sets the password of the account with id. Throws AuthException with AuthFailure.weakPassword for a password the provider will not keep.

override

currentUser() → Future<AuthUser?>

override

deleteAccount(String id) → Future<void>

Removes the account with id. Its credentials no longer sign in.

override

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

signIn(String email, String password) → Future<AuthUser?>

override

signOut() → Future<void>

The server keeps no signed-in person of its own: who is signed in is the session a request carries.

override

signUp(String email, String password, {String? name}) → Future<AuthUser?>

override

toString() → String

A string representation of this object.

inherited

userByEmail(String email) → Future<AuthUser?>

The account whose address is email, compared as the provider stores addresses, or null when there is none.

override

userById(String id) → Future<AuthUser?>

The account with id, or null when there is none.

Operators

Constants

maximumEmailLength → const int

The longest address kept. Longer than any address a mail server delivers to (RFC 5321), and short enough to be a unique key everywhere.

minimumPasswordLength → const int
