[ Widget Preview ] Improve widget inspector support for widget previews ( #168013 )
...
In order to prevent the widget inspector from being able to select and
inspect elements of the widget previewer's scaffolding, this commit
consists of two notable changes:
1) A `debugWillManuallyInjectWidgetInspector` property has been added to
`WidgetsBinding`. Setting this property to true before running the
application will prevent `WidgetsApp` from injecting a `WidgetInspector`
instance into the widget tree, even if the widget inspector is enabled.
This means that the widget inspector will not be able to select and
highlight widgets by default, requiring `WidgetInspector` to be manually
wrapped around widget trees that should be inspectable.
2) The widget_preview_scaffold template has been updated to set
`debugWillManuallyInjectWidgetInspector` to true by default, and to wrap
individual previews provided by the developer with an instance of
`WidgetInspector` to restrict widget inspection to the contents of the
preview.
This change also includes a minor bug fix for situations where
`WidgetInspector` is inserted into an unconstrained context. Previously,
the `WidgetInspector`'s `_InspectorOverlay` would attempt to take up as
much space as possible, causing an overflow. To fix this, the
`_InspectorOverlay` is wrapped with `Positioned.fill(...)` to force it
to take on the same size as its parent `Stack`.
