Description

After the implementation of Null Safety (Pull Request: feat: Implementation of Null Safety #32), the IconComponent that is used on the NavBar and TabBar is rendering a failed image (a black object), but the path and the process of the rendering seems to be correct.

Steps To Reproduce

1. Launch the sample application
2. Click on Start beagle flow
3. Click on any option of the menu (like Button), but for more examples click on TabBar

Expected Results

The icon on the NavBar, or on each TabBarItem of the TabBar, should be a black shaped object.
