Example Concept: In Flutter, unnecessary rebuilds can be minimized by using `const` constructors for immutable widgets, which tells Flutter that the widget's configuration is constant and does not need to be rebuilt. Additionally, using keys like `ValueKey` can help Flutter differentiate between widgets and maintain their state across rebuilds. For state management, using providers or other state management solutions can help isolate state changes to specific parts of the widget tree, reducing the scope of rebuilds.
