Error: No named parameter with the name 'fallbackVsyncTargetTime'.

[jmquilez]

First of all, I'd like to thank everybody working on this astonishing project. I truly believe it will bring flutter to a whole different level of completeness and crucially assist with the creation of more performant and production-ready apps. I am actually trying it out because of micro-stutter issues with a listview of videos, where the reported jank does not appear in the devtools' performance view. As it is not raster nor ui thread jank, I believe it might be related to some of the things that this packages aims to solve.

Describe the bug After installing "flutter_smooth" (downloading and building the custom engine, and downloading the custom flutter framework), building a project with it throws a series of error messages, amid which there is the "No named parameter with the name 'fallbackVsyncTargetTime'" that has been mentioned in other issues recently (#154 , #150 ). Here is the complete error message:

To Reproduce Below I list the steps used to build the custom engine and download the custom flutter framework (I used the "flutter-smooth" branch in both of them, as mentioned here):

1) git clone --branch flutter-smooth https://github.com/fzyzcjy/engine.git smooth_engine

2) cd smooth_engine

3) create ".gclient" file & set its contents to "solutions = [ { "managed": False, "name": "src/flutter", "url": "https://github.com/fzyzcjy/engine.git@465ccd29740625d20ab0cdf2529a9dda19824e99", "custom_deps": {}, "deps_file": "DEPS", "safesync_url": "", }, ]"

4) set DEPOT_TOOLS_WIN_TOOLCHAIN=0

5) gcloud auth login

6) gcloud auth application-default login

7) gclient sync

8) cd src

9) set GYP_MSVS_VERSION=2017

10) set GYP_MSVS_OVERRIDE_PATH=C:\Program Files (x86)\Microsoft Visual Studio\2017\Community

11) .\flutter\tools\gn --unoptimized --> WITHOUT "--no-goma --no-prebuilt-dart-sdk"

12) ninja -C out/host_debug_unopt

13) cd ../../

14) git clone --branch flutter-smooth https://github.com/fzyzcjy/flutter.git smooth_flutter

15) git clone https://github.com/fzyzcjy/flutter_smooth.git flutter_smooth

Expected behavior The app compiling without errors.

Thank you so much for your work and time :).

Hi! Thanks for opening your first issue here! :smile:

[fzyzcjy]

Hi, have you checkout the custom flutter framework and flutter engine? That error looks like some version (custom hack) does not match

[jmquilez]

I apologize for not being able to answer these previous days. Would it be possible to continue the discussion in #182? (just posted a comment there) as I believe both issues are almost the same. Thank you for your help and attention

[fzyzcjy]

Yes, sure!
