SqliteExtension class abstract interface

Information used to load an extension through sqlite3_auto_extension, exposed by Sqlite3.ensureExtensionLoaded.

Note that this feature is not a direct wrapper around sqlite3's dynamic extension loading mechanism. In sqlite3 builds created through sqlite3_flutter_libs, dynamic extensions are omitted from sqlite3 due to security concerns.

However, if you want to manually load extensions, you can do that with a SqliteExtension where the entrypoint is already known. This puts the responsibility of dynamically loading code onto you.

For an example of how to write and load extensions, see

• this Dart test loading it: https://github.com/simolus3/sqlite3.dart/blob/a9a379494c6b8d58a3c31cf04fe16e83b49130f1/sqlite3/test/ffi/sqlite3_test.dart#L35
