Workaround to open sqlcipher on old Android versions. #

On old Android versions, this method can help if you're having issues opening sqlite3 (e.g. if you're seeing crashes about libsqlcipher.so not being available). To be safe, call this method before using apis from package:sqlite3 or package:moor/ffi.dart.

Future<void> setupSqlCipher() async {
  await applyWorkaroundToOpenSqlCipherOnOldAndroidVersions();
  open.overrideFor(OperatingSystem.android, openCipherOnAndroid);
}
