import 'dart:typed_data'; // required for Uint8List

Future<List<Uint8List>> GetByteArray(final int Id) async {
var connection = new PostgreSQLConnection(...); // replace with your credentials

var sqlQuery = "SELECT data FROM table WHERE id = @Id";
List<dynamic> results = await connection.query(sqlQuery, substitutionValues: {
"Id" : id
});

return results;
