Which mobile app dev framework?

Hello all,

I am planning for developing a new mobile app and need suggestion on which mobile app development framework would be best for this use case.

A mobile app that works like a folder/organizer which is initially empty.
A user can import files into it.
Each file when imported results in a single page.
This page can have a mix of items on it. E.g images, texts, links, embedded javascripts, Google maps, etc.

Let's say this is an organiser for greeting cards.
So, if a user has imported 10 files (1 for each greeting card), then user can flip through these cards within the organiser.
Organize them by tagging each of them.
Share them with others
search using some texts.

Would Flutter be suitable for this requirement?

Thanks in advance.
