app_data_state 0.0.3

A new Flutter package to handle state inside apps

DataState

The DataState class is used to represent different states of data loading in a Flutter application. It encapsulates the loading state and any associated exception.

Usage

Importing

To use the DataState class, import it in your Dart file:

import 'package:app_data_state/data_state.dart';

Creating instances

You can create instances of the DataState class using the provided constructors:

final noneState = DataState.none();
final loadingState = DataState.loading();
final fullState = DataState.full();
final partialState = DataState.partial();
final errorState = DataState.error(Exception('An error occurred'));

Methods

The DataState class provides several utility methods to check the current state:

• bool get hasException: Returns true if the state is LoadingState.error.
• bool get isLoading: Returns true if the state is LoadingState.loading.
• bool get isFull: Returns true if the state is LoadingState.full.
• bool get isNone: Returns true if the state is LoadingState.none.

Enum LoadingState

• none: Indicates that there is no data loading process currently happening.

• partial: Indicates that the data loading process is partially complete.

• loading: Indicates that the data is currently being loaded.

• full: Indicates that the data loading process is fully complete.

• error: Indicates that an error occurred during the data loading process.

• These states help in managing and representing the different stages of data loading in a Flutter application, allowing for better control and handling of the data loading lifecycle.

Example

Here is an example of how to use the DataState class:

void main() {
  const state = DataState.loading();
  if (state.isLoading) {
    print('Data is currently loading');
  }
}

Features

• Represent different loading states: none, partial, loading, full, error.
• Encapsulate exceptions related to data loading.
• Provide utility getters to check the current state.

Getting started

To start using the DataState package, add it to your pubspec.yaml:
