How to set chrome browser's flags

Sometimes user wants to enable/disable the chrome flag before running test with chrome browser. If we open a chrome manually and type "chrome://flags" in the address bar, we can see the "flags" shown as below:



If we want to set flag "temporary-unexpire-flags-m83" to "Disabled" with SeleniumPlus, we can create a file "chromeExperimental.dat" containing the following content
{
   "localState" : {
    "browser.enabled_labs_experiments" : ["temporary-unexpire-flags-m83@2"]
   }
}
Then we can start the browser by API StartWebBrowser as below:
StartWebBrowser(url, browserID, SelectBrowser.BROWSER_NAME_CHROME, ..., SelectBrowser.KEY_CHROME_EXPERIMENTAL_OPTIONS, "chromeExperimental.dat")

Then we see that the launched chrome's flag "temporary-unexpire-flags-m83" is disabled


To set the flag to "Enabled", we add @1 at the end of the flag, for example "temporary-unexpire-flags-m83@1"; To set the flag to "Default", we add @0 at the end of the flag, for example "temporary-unexpire-flags-m83@0".
If we want to set multiple flags, we can modify the json file "chromeExperimental.dat" to add more flags, example as below
 
{
   "localState" : {
    "browser.enabled_labs_experiments" : ["temporary-unexpire-flags-m83@2", "same-site-by-default-cookies@0", "cookies-without-same-site-must-be-secure@1"]
   }
}
