storage library

Classes

AppStorage: A singleton class that provides a wrapper around the GetStorage API for simple key-value storage operations.
Batch: A batch is used to perform multiple operation as a single atomic unit. A Batch object can be acquired by calling Database.batch. It provides methods for adding operation. None of the operation will be executed (or visible locally) until commit() is called.
CacheStorage: A utility class for performing basic file operations such as saving, reading, and deleting files in a specified folder. Supports both text and binary files.
Database: Database to send sql commands, created during openDatabase
DatabaseExecutor: Common API for Database and Transaction to execute SQL commands
DatabaseFactory: Basic databases operations
DbHelper: An abstract class that defines the contract for database helper implementations using the sqflite package.
GetStorage: Instantiate GetStorage to access storage driver apis
Microtask
OpenDatabaseOptions: Options for opening the database see openDatabase for details
QueryCursor: Cursor for query by page cursor.
ReadWriteValue<T>
Sqflite: sqflite plugin
SqfliteDarwin: Darwin specific implementation.
SqfliteOptions: internal options.
SqflitePlugin: sqflite Plugin registration.
SqfLiteService: A service class for managing SQLite database operations using the sqflite package.
Transaction: Database transaction to use during a transaction
ValueStorage<T>

Data on T
DatabaseFactoryLoggerDebugExt on DatabaseFactory: Debug extension for Logger.
SqfliteDatabaseAndroidExt on Database: Android only API
SqfliteDatabaseExecutorExt on DatabaseExecutor: Helpers
SqfliteDatabaseExt on Database: Set the journal mode
SqfliteDatabaseFactoryDebug on DatabaseFactory: Debug extension

databaseFactory ↔ DatabaseFactory: sqflite Default factory.
getter/setter pair
databaseFactoryOrNull ↔ DatabaseFactory?: Default database factory.
getter/setter pair
databaseFactorySqflitePlugin → DatabaseFactory: Default factory that uses the plugin.
no setter
onDatabaseDowngradeDelete → OnDatabaseVersionChangeFn: Downgrading will delete the database and open it again.

sqfliteLogLevelNone → int: No logs
final
sqfliteLogLevelSql → int: Log native sql commands

databaseExists(String path) → Future<bool>: Check if a database exists at a given path.
deleteDatabase(String path) → Future<void>: Delete the database at the given path.
getDatabasesPath() → Future<String>: Get the default databases location.
onDatabaseVersionChangeError(Database db, int oldVersion, int newVersion) → Future<void>: to specify during openDatabase for OpenDatabaseOptions.onDowngrade Downgrading will always fail
openDatabase(String path, {int? version, OnDatabaseConfigureFn? onConfigure, OnDatabaseCreateFn? onCreate, OnDatabaseVersionChangeFn? onUpgrade, OnDatabaseVersionChangeFn? onDowngrade, OnDatabaseOpenFn? onOpen, bool? readOnly = false, bool? singleInstance = true}) → Future<Database>: Open the database at a given path
openReadOnlyDatabase(String path, {bool? singleInstance = true}) → Future<Database>: Open the database at a given path in read only mode

KeyCallback = dynamic Function(String)
OnDatabaseConfigureFn = FutureOr<void> Function(Database db): Prototype of the function called before calling OpenDatabaseOptions.onCreate/OpenDatabaseOptions.onUpgrade/OpenDatabaseOptions.onOpen when the database is open.
OnDatabaseCreateFn = FutureOr<void> Function(Database db, int version): Prototype of the function called when the database is created.
OnDatabaseOpenFn = FutureOr<void> Function(Database db): Prototype of the function called when the database is open.
OnDatabaseVersionChangeFn = FutureOr<void> Function(Database db, int oldVersion, int newVersion): Prototype of the function called when the version has changed.
