Google Chrome is the most popular internet browser available across platforms. It has lots of features for users to try on, but some of the features are hidden behind the walls as experimental features. These experimental features may or may not be available in future versions of Google Chrome, but to enjoy these hidden features, you have to enable them through Chrome Flags.
Chrome Flags are not features, per se, but it is a way to activate the new experimental features in Google Chrome. They allow you to test features before they're added to Chrome. The experimental flag features can be used on Chrome browsers running on platforms like Windows, Linux, Chrome OS and Android.
There are lots of Chrome Flags which you can enable on Google Chrome right now. We talk about some of the best Chrome Flags that you can try out right now. Read on!
Auto Dark Mode for Web Contents
Many users prefer using dark mode on their phones, and while Google is expected to roll out this feature in a stable release in the coming months, you can enable Dark Mode under this experiment.
This will automatically render all web content in dark mode, including the ones that don’t support a native dark mode. It is also worth mentioning that since Dark mode is force-enabled on some websites, the content might not be visible at times. 
Supported platforms: Windows, Linux, Chrome OS, Android, Fuchsia, Mac, Android
URL: chrome://flags/#enable-force-dark
Smooth Scrolling
If you are not satisfied with scrolling on your Chrome browser, you can enable this feature for a smoother scrolling experience.

Another useful Chrome flag is site isolation. This flag helps you enhance the security of your browser. With site isolation, Chrome will load each website in its process.
