Flutter App that shows NASA Astronomical Picture of the day (APOD)

NASA Astronomical Picture of the Day (APOD)

A simple Flutter Application that shows a list of Astronomical Pictures in chronological order fetched from NASA APOD API 🚀🛰

Screenshots

Getting Started

Make sure you grab the API_KEY from NASA API.
After you have obtained the api key. Create a new file called api_key.json in assets/ directory.
Copy & paste the following lines into it and make sure to replace the key with your API_KEY

{
    "key": "YOUR_API_KEY_HERE"
}

From here onwards its pretty straight forward. Just cd into the root directory and run flutter run to run the app on your emulator/device.

nasa_apod_flutter's Issues

Restructure the current API Fetch and Display Process

• The current implementation doesn't exactly follow BLoC principles
• Suggestion to refactor and restructure without breaking anything

App Icon required

Add About section

A separate page which shows the list of all contributors for this project and of course details about Nasa API

Improve Documentation

• Add Schema diagram of overall architecture of the app
• Fix grammars and improve the Readme file
• Intro about the structure and flow of the app so its easier for newcomers to go through the app flow

Add Copyright/Owner info

Improve Caching with Local DB

• Suggestion to use sqflite or Hive

Video Playback support

Some responses in url have video

Improve UI / New UI Proposal

Download High Resolution image Feature

• use hdurl field in the JSON response (some don't have it, so automatically download the url ones)
• FAB in detail page does nothing as of now
• Suggestion to make it so that on click would dispatch a background task to download the image with a confirmation dialog

Support for Dark Mode

• Support for Switching between dark and light modes
• Also better colours (changing the app bar/ background colour based on the image)

Write Tests to Mock API and Repository

Support for Zoom View

A photo detail view with pan and zooming

Handle API Failures/Errors

• Handle Errors/Exceptions Gracefully with relevant messages
• Support for Retries on API request fails
• Support for Proper messages on 429 Status code (Rate limit)

Can't compile code.

I added the json file with the API key as suggested in the ReadMe. But, I still can't run the app.

These are the error messages I get.

`Compiler message:
