How "update" FutureProvider?

[FetFrumos]

I have FutureProvider in my app:

 ```
final myFutureProvider = FutureProvider<ProductLoadResult<Data>>((ref) async {
final connectivityResult = await (Connectivity().checkConnectivity());
final netAvailable = connectivityResult != ConnectivityResult.none;
if(netAvailable){
final productsApi = ref.read(productsApiProvider);
final result = await productsApi.getData();
  return ProductLoadResult<Data>(true, result);
}
else{
  return ProductLoadResult<Data>(false, null);
 }

});

therefore, in this provider, I check the network status and if the network is available, I receive data via the API.

using the provider:


       ```
          final apiData =  ref.watch(myFutureProvider);
        
           body: apiData.when(
               data: _bodyForData,
               error: _bodyForError,
              loading: () => const Loader()),
      ```
              
if the network is not available, I display the button. on pressure the following logic:    

   ```
   setState(() {
           //without this line, the value of categoriesFutureProvider is not updated
           ref.invalidate(categoriesFutureProvider);
     });
   ```
     
it works - but I'm not sure it's the optimal logic.

maybe there is a better option? I will be grateful for your help

"if the network is not available, I display the button. on pressure the following logic: "

I wonder why you need setState() in this place. Did you try the following?

TextButton(
                onPressed: () => ref.invalidate(categoriesFutureProvider)
                child: Text('Retry'),
              ),

The other part looks okay, I would propably place the connectivity check in the API or HTTP Client repository and throw a custom exception if there is no-connectivity. Then you would be able to handle the no-connectivity and any other exception in "error: _bodyForError", so you wouldn't need the "if (netAvailable) ...." statement in this and other providers with API requests.
