A more elegant Flutter Dialog solution solves the pain points of many Flutter systems that come with Dialog, making the use of dialog easier! SmartDialog implements Toast and Loading pop-up windows. Toast and Loading will not meet independently, and can exist on your interface at the same time. At the same time, it also provides full customization functions, so you can easily realize what you need Dialog!
