Hey, i am using cli/v2 is there any way to extend flags during execution after parsing 1 specific flag? Like if some flags has dependencies on other flags.

app := cli.NewApp()
app.Flags = []cli.Flag{
	&cli.StringFlag{
		Name: "name",
		Action: func(context *cli.Context, s string) error {
			// some logic here which generates dynamic flags. Is there any way to extend flags?

			return nil
		},
	},
}

if err := app.Run(os.Args); err != nil {
	panic(err)
}

I figured out how to fulfill my need. I can parse needed flag from os.Args and then generate dynamic flags based.
