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. [...]
Check: Adds validation to column.
Column: Column of database.
Constraint: Column constraint.
Database: Database to send sql commands, created during openDatabase
DatabaseDescriber: Describes the database.
DatabaseExecutor: Common API for Database and Transaction to execute SQL commands
DatabaseFactory: Basic databases operations
DBProvider: Provides database.
Default: Set default value to column.
MetaModel: Holds column names.
Model: Model of a row in database.
NotNull: Restricts NULL for column.
OpenDatabaseOptions: Options for opening the database see openDatabase for details
References: Makes column reference another table.
Sqflite: sqflite plugin
SqfliteOptions: internal options. [...]
Table: Table.
Transaction: Database transaction to use during a transaction
Unique: Makes column unique.

inMemoryDatabasePath → const String: Special database name opened in memory
':memory:'

databaseFactory ↔ DatabaseFactory: sqflite Default factory
read / write
onDatabaseDowngradeDelete → OnDatabaseVersionChangeFn: Downgrading will delete the database and open it again. [...]
final
sqfliteLogLevelNone → int: No logs
final
sqfliteLogLevelSql → int: Log native sql commands
final
sqfliteLogLevelVerbose → int: Log native verbose
final

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 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) → Future<Database>: Open the database at a given path in read only mode

OnDatabaseConfigureFn = FutureOr<void> Function(Database db): Prototype of the function called before calling onCreate/onUpdate/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. [...]
