Include a directory with Flutter assets #12944

szakarias · 2017-11-09T14:09:40Z

The flutter_assets directory is meant to eventually replace app.flx.

This PR also changes the way an asset is retrieved. On asset channel queries, engine now returns the path to the asset instead of returning the asset as byte data.

Before merging this I will have another PR ready which can upgrade the project.pbxproj file of existing projects to include flutter_assets.

Engine PR flutter/engine#4343

just assert(bytes is Uint8List). If it's ever NOT a Uint8List this is a serious performance concern.

FYI @xster who's been working on a "flutter project upgrade" mechanism.

Once the engine changes land, this should include the engine roll to the appropriate revision.

Not build_dir?

Nope, I am however considering renaming the option to assets-dir when doing the FLX removal cleanup.

Rename sgtm. And the reason we're putting this in derived_dir rather than build_dir is that we need to reference it from project.pbxproj (like the current app.flx, App.framework, etc.), right?

Yes, exactly. Should have added that, sorry.

I'm probably still at least a week away from a functioning flutter project upgrade mechanism. How does this PR work with flutter projects created in the past?

szakarias · 2017-11-14T08:54:17Z

Old flutter projects will need to get their project.pbxproj updated for this to work. The PR for it is here #13011 .

@szakarias What is the status of this PR?

szakarias · 2017-11-23T08:21:52Z

I am waiting for review of the corresponding engine PR flutter/engine#4343. cc @chinmaygarde.

chinmaygarde · 2017-11-29T23:55:59Z

I have added a few more comments to the engine PR. I am still a bit unclear about how we are going to address the following issues:

How are the *.pbxproj template upgrades going to be applied to existing users of Flutter? I see no indication about providing upgrade guidance or warning in either the engine or framework patches.
- My hacky attempt to copy the resources manually in the xcode_backend.sh build invocation to the directory specified in ${TARGET_BUILD_DIR}/${WRAPPER_NAME}/flutter_assets seemed to work. I grabbed those variables from the Xcode build log by clicking the "Show environement variables in build log." checkbox. Maybe we dont need the templates to change.
Hardcoding a single directory named flutter_assets means we can't have multiple Flutter applications in the same application bundle.

szakarias · 2017-12-11T14:57:01Z

Reverted the change in asset retrieval. We still return assets as byte data instead of the asset paths. I am postponing this to a later change.

With respect to upgrading existing projects, there is this PR #13011.

With respect to having multiple Flutter applications in the same application bundle, I am not sure how hardcoding flutter_assets is worse than the already hardcoded app.flx?

LGTM

BTW, this was checked in when the tree was red. Please avoid checking anything in when the tree is red except for attempts to fix the tree, because it makes it much harder to detect, and later identify, additional failures introduced while the previous failure was ongoing. Thanks!

@Hixie Tree was red because of a test we had identified, but not marked, as flaky. It was so marked a little later (#13542).

Hixie · 2017-12-16T22:46:40Z

Ah, excellent. It's good to leave a message on the PR when that happens so that everyone knows it was intentional. Thanks for the update!
