[ Feature Request ] Add conditional extension

[rakeshlanjewar]

Is your feature request related to a problem? Please describe. Yes, This will eliminate the ugly if-else blocks. I don't know it is feasible or not. Just an idea.

Describe the solution you'd like I want to achieve something like this.

.when(condition,stylesWhenTrue )

example 

'John'.text.size(30).when(1==1, ___ ).color(Colors.white).make()

Additional context This is just an idea that is similar to laravel query builder
