[LVGL + FLOW] eez-flow.cpp toString bug

[hellsge]

Describe the bug
eez-flow.cpp error

To Reproduce
Because i use my own lvgl simulator, maybe you can not reproduce.

Expected behavior

Screenshots
lvgl ui in ezz stdio

I have enable Flow support. But there is no flow in this demo right now.
I think this bug should be unrelated to the UI.
