I have implemented a DialogueBox class which can be static, singleton, service locator, etc.
I have written it as a singleton pattern and implemented it in Unity3d engine. It is a part of a game.
I have ShowDialogueBox method with many parameters. How can I handle it?
The parameters are message, ok button label, cancel button label, has the cancel button or not, actions to be invoked when users click on ok or cancel button.

Is it more suitable to apply Builder pattern for it?

Because the method is not sometimes flexible and I have to provide all parameters.

In addition, my messages are not static and sometimes I need to display a message with parameters like cost value, etc. Therefore, I should add another parameter like params to the method or create the message with params before calling the method?
Also, It is appropriate to pull out Localizer from DialogueBox class?

//DialogueBox.GetInstance().ShowDialogueBox("BuyMessage",()=>{},

 //       ()=>{}, "Buy", "Cancel",true)
