Reusable Style

One of the most convenient benefits of Niku is, you can create reusable styles anywhere in your codebase.

If you come from a web background, this is like a CSS class. If you have some SwiftUI background, this is exactly like a custom modifier.

This is an inspiration to create Niku in the first place. To be able to reuse styling anywhere not limited to a single codebase.

apply()

For style builder, there's apply() which takes another instance itself and extracts and inherits the styling.

final title = NikuText()
  ..color(Colors.blue);

return NikuText("Hello World")
  ..apply(title)

You can also add more styling property after apply the styling.

final title = NikuText()
  ..color(Colors.blue);

return NikuText("Hello World")
  ..apply(title)
  ..fontSize(21);

Multiple Styling

You can also apply multiple styling

final title = NikuText()
  ..color(Colors.blue)
  ..fontSize(21);

final bold = NikuText()
  ..bold();

return NikuText("Hello World")
  ..apply(title)
  ..apply(bold);

Limitation

Although apply will inherits the style, it won't inherit the parent widget and it only accepts an instance of itself.

For Parent Builder, you can use the builder() method to compose multiple parents and reuse it instead.
