CameraButton get partly obscured if bottom keys are used on android 15+ (android 16 and on), when calling ImagePicker.pickImage to grab a image from camera of PickImage tool:

(Picture from Canary Preview medium format)

Normally we add a Padding for theese situations like

return Padding(
      padding: EdgeInsets.only(bottom: MediaQuery.of(context).padding.bottom),
      child: ...

to avoid the button row.

Since ImagePicker.pickImage does the layout in theese situations, you should do similar for this tool.

Same for the other buttons in the tool

The buttons are not aligned or come too near the system buttons.
