I'm repeatedly having the following exception in terminal while trying to add an asset image in the appBar of my Flutter application (running on an Android emulator):

══╡ EXCEPTION CAUGHT BY IMAGE RESOURCE SERVICE ╞════════════════════════════════════════════════════
The following assertion was thrown resolving an image codec:
Unable to load asset: /assets/images/small.png

When the exception was thrown, this was the stack:

Another exception was thrown: A RenderFlex overflowed by 117 pixels on the right.

This is the code of application's home:

Just remove / from your path that you are assigning to Image widget like

Image.asset('assets/images/small.png'),
