From local to global news, the client's news channel offers news related to sports, sound & music, radio, and much more.

Business Challenge - Flutter App Development Agency

Delivering excellence and symmetry in the application with the business through Flutter.

The client wanted the application to match the business environment as well as other application themes. The weather app should be seamlessly connected with the database and servers of the new channel so that the viewers can get the latest update on the weather straight from the channel.

The app must be available on both Android and iOS platforms for all the viewers, just like others. The app must also be intuitively designed for the users with details, such as every hour temperature, sunrise & sunset, weekly forecast, precipitation, humidity & air quality as well as severe weather alert.

Our Solutions - Flutter App Development Company

Enlightening everyday viewers with weather forecasts at their fingertips.

A3logics decided to develop the application on Google's Flutter. Using the business logic component design pattern, the architecture of the weather application was made and showcased to the client. The application constituted of the following -

Weather Page

The view part of the application as soon as the viewer clicks on the app icon. The page displayed a lot of data systematically and interactively, which is easy to understand and grab. The page displays the real-time weather conditions information, animated phases of the moon & sun, a selection of up to 10 cities for monitoring their weather air quality, humidity & precipitation, a weather map, and a weekly weather forecast.

Component Bloc

This feature of the application consists of business logic. The app will be provided data through streams that handle user input events. In every bloc component of the application, the data gets fetched from the repository and sent to the data stream. In order to prevent memory leaks, our developers created a disposal method for the bloc class that can be called from the widget's dispose method.


A repository was made that held the responsibility to provide uninterrupted data to the upper layers of the application. Our developers used JSON to fetch the data with the help of API and then convert the data into Dart (Flutter) objects. The repository was able to cache the current data to the local database in order to provide the latest data despite the network unavailability.


API Data Packages were used by the developers in order to fetch relevant data such as severe weather, lifestyle indices, historical weather data, traffic data, seasonal & sub-seasonal forecasts, and others. Through a simple class with a static method, reports could be easily fetched from the news channel database or repository.


The feature offers 12-hour precipitation maps for the country/region that the viewer has selected. Temperature and precipitation data is sourced from the repositories connected to the database and satellite that source the national weather channels.

They ensure that the feature updates the source code files in time for the continuous flow of information regardless of changes. Developers use Hot Reload to compile with other languages for cross-platform feature development.

  • Migration and Upgradation

    With Flutter, developers can seamlessly migrate the data of other applications to a brand new one. Package libraries offer backward compatibility. Our developers use FlutterPlugin to encourage swift upgrades.
