list_bloc's Issues

[flutter_list_bloc] Integration/Widget tests for the bloc builder widgets

We have widgets in flutter_list_bloc that works with list_bloc.

• Need to add integration/widget tests for the bloc builders widget which would test that if the bloc states are changing properly and reflecting with the widgets properly.

create unit tests

Create unit tests for list_bloc and flutter_list_bloc packages.

Create unit tests for `list_bloc` package

This issue is related to #2 and tracks the progress on implementing unit tests for the list_bloc package.

A minimum of 100% test coverage is required.

[list_bloc] Implement remove, add, replace method for list_cubit with example usage

• We need to enhance ListCubit class to support addLocally, removeLocally, replaceLocally etc method to update the state of the Cubit.
• Inside the ./example folder create a simple flutter project showcasing how to use the methods.

[openapi_repository] Migrate to dio 5.0.0

create pet store example

The primary goal of this library was to create a simple abstraction layer between an open API client automatically generated by https://openapi-generator.tech/docs/generators/dart-dio/ and the UI layer using BLOC architecture.

We do this internally at our company, and it would be great to have an example of how to use this library with a standard Pet Store example from

We should create an example of using ListBloc and PaginatedBloc using dart-dio api generated with https://openapi-generator.tech/

In the example we should show how to generate https://openapi-generator.tech/docs/generators/dart-dio client from the Pt Store example swagger.yaml then we should create a DataRepository and PagedRepository based on that client and finally show how to use it in a simple Flutter application that would display the pets from the Pet Store using this library.

[flutter_list_bloc] Create an example app showcasing usage of the widgets.

Create an example app for flutter_list_bloc package. It should demonstrate the usage of all the widgets available in flutter_list_bloc. Please provide in-code documentation of each widget and when to use the widget.

• DataBlocBuilder
• ListBlocBuilder
• ListViewBlocBuilder
• ContinuousScrollBuilder
• ContinuousListViewBlocBuilder
• PageViewBlocBuilder
• SliverListBlocBuilder

Goals:

• Showcase example use-case of each widget from flutter_list_bloc.
• Write in-code documentation with the use case of the widget.
• Example code must be plain and simple, remember to keep the structure flat and no nesting file structure.
• It is just an example app so write minimal code to showcase the usage. No need for 3rd party packages/plugins.
• Use DRY principle wherever applicable.
• Bonus Task: #19

Please create a PR for review when done. Keep the commit history clean, and use atomic commit pushes.

[list_bloc] Reloading uses current offset to reload, which can return empty list

Currently reloading takes the current state's filter
Code Link

  Future<void> reload([F? filter]) => super.load(filter);
  // in data_cubit.dart
  Future<void> load([F? filter]) async {
    final f = filter ?? state.filter;
  // etc...

If the user scrolls to the last item, then after reaching the last item the ContinuousScrollBuilder will take the total item's length as the current offset and try to fetch items. As of this moment, the filter's offset value becomes the length of the items.
Code Link

      final offset = _cubit.state.data?.length ?? 0;

Then if we reload the list the cubit will return 0 items and the previously loaded items will vanish due to the wrong offset value.(This offset value is the last items offset after that no items are available to fetch)
