List of files in flutter

Question

I have images and I want to load them to my appplication. my_app/lib/... - here my source files my_app/assets/images/... - here my images

I need to get list of files

Answer 1

I keep a json file inside assets which records the file tree of assets folder.

When file list is needed, I just read from the json file.

Such json file can be easily generated by code.

However, this does not solve your problem directly when u have 5-10k images. Only one json file might be too large to read.

Images should be grouped and recorded in separated json files.
