Comprehensive Weather Application Development Project with Flutter

Short Description

In this project, I developed a mobile-focused weather application using Flutter that displays current weather, hourly data, and a 5-day forecast.

Problem

Simply providing the current temperature is not sufficient for weather information. I wanted to display the intra-day changes and a few days' forecast in a single flow with a simple mobile interface.

Solution

I divided the application into components within Flutter and fetched the data via the OpenWeather forecast endpoint. In the model layer, I parsed city and forecast data. On the screen, I set up the current conditions, hourly cards, and an expandable/collapsible 5-day forecast section. I used flutter_dotenv for environment variables and included the location retrieval infrastructure, but I used a hardcoded city value for the main flow.

Result

The outcome is a well-organized sample project that clearly demonstrates API consumption, data modeling, and a component-based Flutter screen structure. I combined real-time and forecast-oriented weather experiences in a small project.
