writeTransaction
Opens a read-write transaction.
This takes a global lock, ensuring that only one write transaction can execute against the database at a time, even across separate database instances for the same file.
Statements within the transaction must be done on the provided PowerSyncTransaction - attempting statements on the database instance will error cause a dead-lock.
Return
The result of the callback.
Parameters
callback
The callback to execute within the transaction.
Throws
If a database error occurs.
If the operation is cancelled.
