v1.0.0

First release candidate for a stable release containing the Spacing utilities and a couple of minor improvements.

Breaking Changes

• CommonLayout and GranularLayout value function now requires the type T to extend from Object, not allowing
  the return of null values (which threw a null access in specific scenarios). This was intended but the
  type-inference allowed nullable types when not enforced by Object;
• CommonLayoutWidget/GranularLayoutWidget constructors requires a resolverBuilder instead of a resolver.

Added

• Unit and Widget tests for all the features provided in layoutr;
• maybeValue in both CommonLayout and GranularLayout;
• Spacing, RawSpacings and SpacingsInheritedWidget with utilities (SpacingMixin, SpacingHelpers and
  SpacingPaddingHelpers);
• LayoutResolverInheritedWidget, base InheritedWidget for all LayoutResolver implementations;
• Both CommonLayoutWidget/GranularLayoutWidget:
  • accept a new optional spacings argument that allows responsive and type-safe spacing alongside the usual resolver;
  • withResponsiveSpacings for a fine-grained constructor of breakpoint-specific spacings.
• split_view example.

Updated

• Both CommonLayoutWidget/GranularLayoutWidget can live independent from a MediaQuery parent widget (by using a
  LayoutBuilder);
• Restructured the example folder to a more realistic usage (also added a ton of comments to the respective examples);
• README.md to reflect the new Spacing features.

Fixed

• LayoutResolver.closestValue now throws a descriptive ArgumentError for empty dictionaries;

v1.0.0-nullsafety.0

First library release, everything already documented in README.md.

For a stable release, just the tests and a little improvement on examples remains.
