open method

@override void open({ Function? populateFunction, })

Open the database or create a new one.

If supplied the populateFunction is used.

For sqlite this happens if the db didn't exist, while for postgres the function is executed no matter what, if available.

Implementation

@override
void open({Function? populateFunction}) {
  _populateFunction = populateFunction;
  bool existsAlready;
  if (_dbPath == null) {
    _db = sqlite3.openInMemory();
    // _db = Database.memory();
    existsAlready = false;
  } else {
    var dbFile = File(_dbPath!);
    existsAlready = dbFile.existsSync();
    _db = sqlite3.open(_dbPath!);
    // _db = Database.openFile(dbFile);
  }
  _isClosed = false;
  if (!existsAlready && populateFunction != null) {
    // db is open already, we can use the wrapper for the create function.
    populateFunction(this);
  }
}
