Check your database inspector to know if the table 'countries' really exist.

If not you need to recreate it in your Database Helper.

Getting Data Back from Async Future function in Flutter

Asked 2021-Jun-11 at 14:13

I'm new a newbie in Flutter and kinda struggling a bit while handling the asynchronous and (Future methods). So, after getting data correctly from the database and populating it in the Users object want it to use in widgets. However, I'm not sure about how to get data back from _query method.

You are indeed calling your Future but you are not retrieving the return value from it. Try to expand the onPressed function in order to save the data:

You are using appendingPathExtension. That is for adding an extension to a filename. You meant appendingPathComponent, which is for adding an entire filename (or other path component) to a URL.

That is why you are seeing a . between Documents and your filename, rather than a /, in the path shown in your error message. The simulator will blithely create a file called Documents.playToysDb.sqlite in your app’s root directory, but a device cannot. It expects it to be within the Documents directory, resulting in the failure when trying to create that file.

You asked about the correct way to get the database URL. A few observations:

You asked about urls(for:in:)[0] vs url(for:in:appropriateFor:create:). I would use the latter.
I would advise using .applicationSupportDirectory rather than .documentDirectory. The former is for the app’s support files. The latter is intended for user-facing files, which is not appropriate here. You can use .documentDirectory, but I would not advise it.
I would also avoid repeating this open in createDB and openDatabase. In fact, I would have a single method that would try to open the existing database, and if it fails, only then create the database and create/populate the tables.
Implicit in the above point, I would advise sqlite3_open_v2, in which you can chose to create a blank database or not. So I call it first without SQLITE_OPEN_CREATE (which, if successful, I know the database has already been created). Only if that fails do I try it again with that option (and then proceed to create the necessary tables).
