How to handle the images efficiently as assets in pubspec.yaml?

Question

So I have my project that has 20 folders and each folder has 10 images, I need to animate the images.

Generally we assign images in flutter like below,

image1.jpg

asset:
  - assets/images1.jpg

So Do I have to assign all these images as assets like above? Or is there any way to handle large set of local images in flutter?

Solution

To include all assets under a directory, specify the directory name with the / character at the end:

flutter:
  assets:
    - assets/

Note that only files located directly in the directory are included. To add files located in subdirectories, create an entry per directory.
