Refactored the `PlexOptimizedImage` widget to move the `resolvedDimension` helper function out of the `build` method and into a top-level private function. Defining functions inside a `build` method causes a new function object (a closure) to be allocated on every widget rebuild. For frequently rebuilt widgets like images in a list, this creates unnecessary memory churn and adds overhead for the garbage collector. This change prevents the repeated allocation of the function object, reducing memory churn and CPU overhead during renders. While a micro-optimization, it contributes to smoother scrolling and better overall performance, especially in image-heavy views.

💡 What: Refactored the
PlexOptimizedImagewidget to move theresolvedDimensionhelper function out of thebuildmethod and into a top-level private function.🎯 Why: Defining functions inside a
buildmethod causes a new function object (a closure) to be allocated on every widget rebuild. For frequently rebuilt widgets like images in a list, this creates unnecessary memory churn and adds overhead for the garbage collector.📊 Impact: This change prevents the repeated allocation of the function object, reducing memory churn and CPU overhead during renders. While a micro-optimization, it contributes to smoother scrolling and better overall performance, especially in image-heavy views.
🔬 Measurement: The improvement can be observed by profiling the application's memory usage in Flutter DevTools. Before the change, memory allocation would show an increase in closures during scrolling. After the change, this specific allocation is eliminated.
