When I reading the code of flutter. I find some code in framework.dart like
Timeline.startSync('Build', arguments: timelineWhitelistArguments);
Timeline.finishSync();
I found the document in this website
https://api.flutter.dev/flutter/dart-developer/Timeline-class.html
But I still don't understand what is the purpose of this class.
It's used to check the app performance on a timeline in Flutter DevTools.
You can read more about it here: Tracing Any Dart Code Performance
EDITED
Also found a good article about profiling Flutter apps using timelines at medium.

I am trying to create a flutter app using the ML model from the below link.
https://www.tensorflow.org/lite/models/style_transfer/overview
I haven't played with Flutter but there are some promising articles article 1 article 2 article 3 that gives code snippets to insert tensorflow lite dependencies, to make assets folder and load models. You can check them and I hope you get a first idea how to proceed. Style transfer is a medium to hard coding project though. I suggest to start from simpler tasks as classification problems.
Happy coding
I have used this style_transfer model in flutter app before. unfortunately, I've lost that code (I did not use git). But I can give suggestions on that.
For using this custom model you will have to use https://pub.dev/packages/tflite_flutter.
The trick here is you will have to see model's input shape (image_shape=(384,384,3), style_shape=(256,256,3) and output size (shape=(384,384,3) and also shape of bottleneck). You can resize image using https://pub.dev/packages/image.
with these two, you are good to go. Sorry for bad english and I know I am too much late but maybe someone else will find it useful.
Happy coding!
Edited: So I have found the code. I stored a copy of it in my google drive. I have uploaded it on github https://github.com/Rizwan2613/style-transfer. Please do read Readme file. Thanks
There is a recently published flutter plugin for integrating an arbitrary TFLite model.
https://pub.dev/packages/tflite_flutter
Please see the README of the pub package and see how you can bundle the .tflite models and how to load / run them in flutter.
There is a blog post on how to use this flutter plugin, but it uses a different model (text classification) as an example.
https://medium.com/#am15hg/text-classification-using-tensorflow-lite-plugin-for-flutter-3b92f6655982
You can upload custom tensorwflow model to firebase ML KIT (custom tab), and integrate with firebase API in your flutter project.
Looking for a UI integration test strategy for Flutter. We'd love to use Silenium/Ghost Inspector but seems that is not practical due to lack of html id's or CSS classes in Flutter (Add id or name property or other means of identification for Flutter Web applications?). Or has anyone found a way round that?
In the meantime Flutter Driver has only very basic documentation for simple tests like finding a button and pressing the button. Anyone know if I can do other operations like navigate to a specific page (e.g. using a # url fragment), test a link which leads to an external site, check visual setup of the page against an image, and other such tests which would be standard in Silenium and the like.
Thanks!!
Well seems Flutter Driver is still very limited so I have instead found a strategy for using Selenium, posted full details here:

I have read in flutter.dev about global_configuration it is:
"A flutter package for managing different configurations by merging them together and making them available everythere inside the app via a singleton."
this link of global_configuration library
but honestly i didn't understand much about what the library dose i searched in youtube and google didn't find much about it if you can tell me where to use it and what its benefit i would very glad and thank you..
I have seen official flutter firestore material only in pub.dev
But there even wasn't a single sentence about getDocuments().
Which site should I look at if I want to do a full formal study on this?
I have already seen cookbooks on flutter dev.
Not much to study, there is even implementation on API refrence. However its just few lines, but I don't know what more there could be...
You can get there from package main page, on the right.
What I am searching:
A tool or an open source project for creating a theme in flutter.
There must be a collection of all widgets on an app to try a theme on.
(Please help me to redirect this question to another place or refactor the question if it is not fitting the platforms standard)
I heard of Panache, where it basically gives you the final code after your review everything:
