SearchScreen doesn't show CircularProgressIndicator first #15
Description
When SearchScreen requests network data, it first displays No results.
Because the list is initialized by default, if the network data is not loaded, the returned list will cause data.length to be 0, and then display No results.
So consider trying not to initialize the list and let it return null.
Then consider displaying CircularProgressIndicator when data == null.
And when data.length == 0, displays No results.
