Properties
- closed → bool
-
Returns true if the connection is closed
no setteroverride
- hashCode → int
-
The hash code for this object.

- runtimeType → Type
-
A representation of the runtime type of the object.

Methods
-
close(
) → Future< void> -
computeWithDatabase<
T> (Future< T> compute(CommonDatabase db)) → Future<T> -
Run a function within a database isolate, with direct synchronous access
to the underlying database.
inherited
-
execute(
String sql, [List< Object?> parameters = const []]) → Future<ResultSet> -
Execute a write query (INSERT, UPDATE, DELETE) and return the results (if any).
inherited
-
executeBatch(
String sql, List< List< parameterSets) → Future<Object?> >void> -
Execute a write query (INSERT, UPDATE, DELETE) multiple times with each
parameter set. This is faster than executing separately with each
parameter set.
inherited
-
get(
String sql, [List< Object?> parameters = const []]) → Future<Row> -
Execute a read-only (SELECT) query and return a single result.
inherited
-
getAll(
String sql, [List< Object?> parameters = const []]) → Future<ResultSet> -
Execute a read-only (SELECT) query and return the results.
inherited
-
getAutoCommit(
) → Future< bool> -
Returns true if auto-commit is enabled. This means the database is not
currently in a transaction. This may be true even if a transaction lock
is still held, when the transaction has been committed or rolled back.
inherited
-
getOptional(
String sql, [List< Object?> parameters = const []]) → Future<Row?> -
Execute a read-only (SELECT) query and return a single optional result.
inherited
-
noSuchMethod(
Invocation invocation) → dynamic -
Invoked when a nonexistent method or property is accessed.
inherited
-
readLock<
T> (Future< T> callback(SqliteReadContext tx), {Duration? lockTimeout, String? debugContext}) → Future<T> - Takes a read lock, without starting a transaction.
-
readTransaction<
T> (Future< T> callback(SqliteReadContext tx), {Duration? lockTimeout}) → Future<T> - Open a read-only transaction.
-
refreshSchema(
) → Future< void> - Ensures that all connections are aware of the latest schema changes applied (if any). Queries and watch calls can potentially use outdated schema information after a schema update.
-
toString(
) → String -
A string representation of this object.
inherited
-
watch(
String sql, {List< Object?> parameters = const [], Duration throttle = const Duration(milliseconds: 30)}) → Stream<ResultSet> - Execute a read query every time the source tables are modified.
-
writeLock<
T> (Future< T> callback(SqliteWriteContext tx), {Duration? lockTimeout, String? debugContext}) → Future<T> - Takes a global lock, without starting a transaction.
-
writeTransaction<
T> (Future< T> callback(SqliteWriteContext tx), {Duration? lockTimeout}) → Future<T> - Open a read-write transaction.
Operators
-
operator ==(
Object other) → bool -
The equality operator.
