Currently you can load from an AssetBundle, and get the data inside the asset. However, in some cases you need to pass the path to the actual file holding the asset data; for example if you want to play back a video using the video_launcher plugin.

    @mit-mit @mravn-google I'm leaving this in the current milestone since it seems like video-related work, but please don't hesitate to move it out if it's not something you think we'll get to in the next few months.

    Yes, we should keep this. Should be fairly easy once the flx work completes.

    Is there a workaround to get the root path of the asset directory other than getting it with a MethodChannel?

    No, but we are in the process of redesigning our asset API and the plan is to make it possible to get the path of a given asset. Is there a particular use case that you would like support for?

    No, my use case was to be able to get the absolute path of a video inside the assets in order to load it with the video player plugin

    Posse had a similar issue where after selecting an asset from Flutter, there was no easy way to pass that asset reference to the native side without reading out the asset and shuffling all the bytes across platform channel.

    Yes, that's the same issue. We hope that @szakarias can get to this fairly soon

    I also have a use case for detecting whether an asset is a part of the bundle and if not, fetching it from a remote source.

    I am currently working on how we handle assets on Android which will hopefully fix the slow startup, reduce the installed size and also make it possible to get a handle on an asset in the APK, which can be passed on, for instance to the video player.

    Fixed, see the documentation.

    Any possibility of accessing the data through as a normal 'File' in dart?

    Example:

    File.new('assets/sqlitedatabase.db') ?

    I'm still not clear on how this was fixed. I'm trying to bundle some PDF files for displaying in my app and need the absolute path to them in order to open them. I don't see anything in AssetBundle documentation that gives me the path to them.

    The original scope of this bug was to offer an asset API for getting assets paths on the host platforms. Documentation was added for Android and iOS here:

    https://flutter.io/docs/development/ui/assets-and-images#android
    https://flutter.io/docs/development/ui/assets-and-images#ios

    It sounds like there is a request to have a similar API on the Dart side. That sounds reasonable, but I suggest you open a new issue for that request.

    Thanks for the explanation @mit-mit now it's clearer. I misunderstood the scope of this completely. Will reopen another ticket

    I have another use case and it is a rather simple one. Theming. I want an automatic way to get an asset path using a dark asset variation if available, otherwise using the normal path. So I need a fast, synchronous way to check for the existence of an asset without loading it. The minimum building block I need to implement this is to get the root path for assets. I can add functionality to my plugin to do this but this seems like a basic feature that should come packaged with Flutter automatically.

    My use case is bundling a test video in my repo to use for a mock video picker service so i can do things like golden test thumbnail/film-strip widget that takes a file as argument. I don't see a way to achieve this without being able to get the path of an asset.
