Why should you avoid creating objects inside the onDraw method in a custom UI element?

The onDraw method in a custom UI element is called very frequently — during each screen update or state change. Creating new objects inside onDraw leads to:

• Frequent memory allocation and garbage collection, which reduces performance and can cause UI lag.
• Increased system load due to constant garbage collector activity.

Therefore, it is recommended to create objects (such as brushes, fonts, paths) once during component initialization or when parameters change, and use already created objects for drawing in onDraw. This helps make rendering more efficient and smooth.
