iOS - Memory issues

[jjboy91]

Hello,

I'm currently working on optimizing my app.
When I'm monitoring the app's memory in DevTool it's showing around 20MB of memory usage.

However, when I'm running the same app via XCode, it's showing 250MB of memory usage or more and around the same value via Instruments or on an iOS app that shows the memory consumption on the device.

What could explain DevTool not showing the right values ?

Also I notice that during a pushAndReplace call, the dispose method was called but the used memory wasn't released.

Where should I look or what should I add to that method so that the page's widget are properly released ?

Thanks

flutter doctor -v
