I am learning Angular, and I have discovered pipes, which not only seem very useful but should also be much more RAM-efficient than functions for data transformation. Is there an equivalent of Angular pipes in Flutter? Or is there something more efficient than functions when I have to do data transformation?
In Flutter I have not seen a concept exactly similar to Angular's Pipe. I think we will not have this kind of concept because Flutter is based on the Declarative UI philosophy without separation of the definition of views with different languages such as HTML/Typescript/CSS.
An Angular pipe is just an invocation of a typescript function from the HTML template. This concept exists because we have this HTML/Typescript separation.
If your needs are to transform a string or a number, you can use the Dart extension concept. See https://dart.dev/language/extension-methods, this may eventually help you.
