I want to Create A Photo Saving App PLease Help!

I am Creating an App In which the user can upload their passes ,tickets, important cards and quickly see them without wasting their time after closing the app when they come back they can see the things they had uploaded.

For this help me out how can this work

Use image picker and tinydb. This way you can code the app to make a list of images and then the user can choose from the list using list picker and you can save the list using tinydb. Also to display use canvas.

See for example

I am the User and I am Uploading my Movie Ticket to the App and Close the App and When i go to theatre i open the App and See my tickets

Will it work ?

Yes, it will because you are saving the tickets using tinydb
