Loading package_dict from Single .uasset Without Provider?

[k----n]

How can you extract the package_dict from a single .uasset file?
The .uasset file lives in a path like: /SpaceTradingShooter/Content/Blueprints/AI/BB_AI_Ship.uasset

This is related to #11 which writes:

Use LegacyPackageReader directly

pyUE4Parse/UE4Parse/Assets/PackageReader.py

Line 80 in 1c7b64c

class LegacyPackageReader(Package):

To use initialize LegacyPackageReader, you need a to pass a BinaryStream.

The first issue is that by directly initializing a BinaryStream for the LegacyPackageReader, you will not get the mappings attribute in the BinaryStream.

pyUE4Parse/UE4Parse/Assets/PackageReader.py

Line 90 in 1c7b64c

self.reader.mappings = uasset.mappings

The second issue is although it seems like you can initialize LegacyPackageReader without a provider, it will error out because set_ar_verion uses None and has no Versions attribute.

pyUE4Parse/UE4Parse/Assets/PackageReader.py

Line 91 in 1c7b64c

self.reader.set_ar_version(provider.Versions.UEVersion)

Check this info: #23
I also needed to check a single asset, so I modified some code.
Worked for me, exporing a Texture2D from UE 4.26 assets.

ok also #14 could help, setting BinaryStream.mappings to None explicitly and creating provider passing the path to the uasset.
So the DefaultFileProvider acts like a generic container I guess, not only dedicated to .pak or .utoc.
