Methods
-
delegateFor(
{required FirebaseApp app, String? databaseURL}) → DatabasePlatform -
Enables delegates to create new instances of themselves if a none default
FirebaseAppinstance is required by the user. -
getChannelArguments(
[Map< String, Object?> ? other]) → Map<String, Object?> - Returns any arguments to be provided to a MethodChannel.
-
goOffline(
) → Future< void> - Shuts down our connection to the Firebase Database backend until goOnline is called.
-
goOnline(
) → Future< void> - Resumes our connection to the Firebase Database backend after a previous goOffline call.
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
purgeOutstandingWrites(
) → Future< void> - The Firebase Database client automatically queues writes and sends them to the server at the earliest opportunity, depending on network connectivity. In some cases (e.g. offline usage) there may be a large number of writes waiting to be sent. Calling this method will purge all outstanding writes so they are abandoned.
-
ref(
[String? path]) → DatabaseReferencePlatform - Gets a DatabaseReference for the root of your Firebase Database.
-
setLoggingEnabled(
bool enabled) → void - Enables verbose diagnostic logging for debugging your application. This must be called before any other usage of FirebaseDatabase instance. By default, diagnostic logging is disabled.
-
setPersistenceCacheSizeBytes(
int cacheSize) → void - Attempts to set the size of the persistence cache.
-
setPersistenceEnabled(
bool enabled) → void -
Attempts to sets the database persistence to
enabled. -
toString(
) → String -
A string representation of this object.

-
useDatabaseEmulator(
String host, int port) → void - Changes this instance to point to a FirebaseDatabase emulator running locally.
Operators
-
operator ==(
Object other) → bool -
The equality operator.

Static Properties
