asset_path_not_string
Asset paths are required to be file paths (strings).
Description
#The analyzer produces this diagnostic when an asset map contains a path
value that isn't a string.
Example
#The following code produces this diagnostic because the asset map contains a path
value which is a list:
yaml
name: example
flutter:
assets:
- path: [one, two, three]
flavors:
- premium
Common fixes
#Change the asset
map so that it contains a path
value which is a string (a valid POSIX-style file path):
yaml
name: example
flutter:
assets:
- path: image.gif
flavors:
- premium
