I would like to pass 2d array string as an argument between fragments.

Can't find that option in arguments, so I've changed argType manually in nav_graph.xml

<argument
            android:name="rowData"
            app:argType="string[][]" <- changed 
            app:nullable="true" />

but then I get an error in self generated args file

error: ']' expected
 array = new string[][__array.length];

Does safe args supports String[][] or not yet? Should I use normal bundle instead?

I have no idea how safeargs works, but it would appear you need to add the first dimension (and capitalize `String`) – user Jan 07 '21 at 19:07
What do you mean by capitalize? – user15921 Jan 07 '21 at 19:09
Not supported please check [here](https://developer.android.com/guide/navigation/navigation-pass-data#supported_argument_types) – Zain Jan 07 '21 at 19:26
Thanks for link. Like i thought, we need to wait. – user15921 Jan 07 '21 at 19:29

`Bundle` doesn't support `String[][]` and Safe Args is just a wrapper around that. How were you expecting it to work? – ianhanniballake Jan 07 '21 at 19:34
