WidgetInspectorModifier class

A widget that enables inspecting the child widget's structure.

Select a location on your device or emulator and view what widgets and render object that best matches the location. An outline of the selected widget and terse summary information is shown on device with detailed information is shown in the observatory or in IntelliJ when using the Flutter Plugin.

The inspector has a select mode and a view mode.

In the select mode, tapping the device selects the widget that best matches the location of the touch and switches to view mode. Dragging a finger on the device selects the widget under the drag location but does not switch modes. Touching the very edge of the bounding box of a widget triggers selecting the widget even if another widget that also overlaps that location would otherwise have priority.

In the view mode, the previously selected widget is outlined, however, touching the device has the same effect it would have if the inspector wasn't present. This allows interacting with the application and viewing how the selected widget changes position. Clicking on the select icon in the bottom left corner of the application switches back to select mode.
