GranularLayoutWidget class
Provides its child with both GranularLayout and the breakpoint-specific RawSpacings
All RawSpacings are optional and if none is provided, it uses the default values found in SpacingsInheritedWidget.defaultSpacings. These spacings act like an auxiliar set of fields that:
- help the related code to be less prone to hardcoded values (provides type-safety with the usage of Spacing);
- alongside the provided utilities, makes handling spacings less verbose by handling the proxying the logic to this instance's resolver.
Because GranularLayoutWidget uses a LayoutBuilder
to get its device constraints, no MaterialApp
(or
MediaQueryData
) is required above/below this widget.
