I'm making an app which has a feature to upload a pdf file through the app and another user can also download the uploaded file and use it, so can anybody tell me how to do it?
You can create a Server Side or Admin App to upload pdf to Firebase by using Admin Sdk. Then You can use Firebase Storage to upload files then retrieve pdf url from storage and save it to Firebase Database. After that you can retrieve that data and download it from database by using Download Manager.

What's the easiest way to transfer a file between two apps running on two different devices? The app is written in Flutter.
You can do that using a database. File will be saved on cloud and from your app you can update it.
Like from X device you read the file parse it to JSON and POST to database.
Then from Y device you can request to database to return that file. That will be returned as JSON than you can read and map at your model and access the file datas using yourModel.yourField() .
You can store your files on a Database such as Cloud Storage for Firebase which allows you to store different file formats
You can then add more files from any device running your Flutter App & make network calls

I am making an app in a college project. I am using firebase for the first time for authentication. What is the best way of storing images for users profiles?
When the are on their profile page I want them to be able to add a picture (like whatsapp for example) but I'm unsure how this works with firebase
Thanks for any help in advance
Firebase have a Cloud Storage too.
If you need to save a profile pic, you can add an image on firebase cloud storage and save image URL in your real-time database.
In this way, when you load user profiles you can retrieve information and load image by URL (you can use Picasso library to make it easy)

I am creating an offline android application with bus routes. The database will be updated frequently and the user should only download and import the database file only. How is this possible. My database file is stored in assets folder.
You should create a signed apk and update your application on play store each time your database changes. There is no partial update. However, play store would be sending delta updates so it is not something you have control on and should not be worried about it.
