Features

• macros: Every widget that derives Declare will automatically implement a macro with the same name to declare a function widget using it as the root widget. (#651 @M-Adoo)

• core: BuildCtx::get() and BuildCtx::get_mut() have been added to facilitate access from anywhere within a build context. (#650 @M-Adoo)

Fixed

• core: The Provider might be missing in a pipe class. (#648 @M-Adoo)
• core: The child generated by the class may not be mounted. (#648 @M-Adoo)
• widgets: Changing the flex of Expanded does not trigger a relayout. (#652 @M-Adoo)

Breaking

• core: function widget no longer requires a &mut BuildCtx parameter. (#650 @M-Adoo)
