QUESTION

ANSWER

Use path_provider_ex package, which provides root and app files directory for both "external storage" (internal flash) and SD card (if present), as well as available space for each storage.

I am trying to connect to a static database as it is explained in this answer. I therefore created an asynchronous function that looks like this:
...ANSWER
Answered 2020-Oct-07 at 21:30Depending whether you need to do this every time and the database could grow, or whether it's a one-time operation (which it seems like it might be?) and the database is small enough that it's not going to take long to query it, there are different approaches I'd take.
If it's a one-time per install sort of thing and the database will always be small, making the user wait while it copies the file across probably isn't a huge deal. In that case I'd do something like this:
QUESTION
I have a local sqlite database saved in asset, which when the app open, it will be copied. When there is a new version of the database, the old file should be replaced. So what I do is simply copy the file again. This method has no issue on simulator and I successfully updated the database. However, in real device, the database failed to be copied.
I am using the following code to initialized the database

QUESTION
I am having trouble accessing files saved in getApplicationDocumentsDirectory
on android only, I keep locale, theme and assets files stored there and when booting up the app those files are always inaccessible and as a result the app does not load, I tried using shared_prefs
to track a first load scenario to use the files in assets/
and then later use the ones download but that seems to be an unreliable fix as at 2nd run they also inaccessible.
The only thing that seems to work reliable is the theme.json, but both copy functions run through the same helpers so what copies the theme over is what copies the locale over. Theme is loaded up in main.dart but the locale is loaded up with EasylocaLizationDelegate
and if the files are in Document storage it can never load them up.
None of these issues are present on iOS, does anyone know of any special tricks to make this work for android, I have tried google but not really sure what to search for.
...ANSWER
Answered 2020-Feb-24 at 08:52I eventually realised that while not an issue on iOS, using rootBundle.loadString
does not work for document storage on Android.
I needed to replace that bit with
