Query related to resource id in appium desktop inspector(app works in both ios and android)


I am trying to automate the flutter developed app using appium.

So, In part of that i am getting locators using appium inspector but while inspecting the flutter developed app the resource id is showing as blank.

But i am not sure why its showing blank.

Note: trying this on android
