The following _CastError was thrown building

Environment

ios

Version:
layout: ^1.0.2

Description

I'm having a red error screen when wrapping Layout around MaterialApp and using context.layout.breakpoint

Here is the error :

The following _CastError was thrown building FwpApp(dirty, state: _FwpAppState#4edf4):
Null check operator used on a null value
...
The relevant error-causing widget was:
  FwpApp FwpApp:file:///Users/pierrebresson/Documents/Code/fwp/lib/setup_app.dart:53:22

When the exception was thrown, this was the stack:
#0      Layout.of (package:layout/src/layout.dart:55:68)
#1      LayoutBuildContext.layout (package:layout/src/layout.dart:163:35)
#2      _FwpAppState.build (package:fwp/app.dart:129:18)

Which I believe is caused by the ! operator inside 'src/layout.dart' line 54 :

static LayoutData of(BuildContext context) => context
      .dependOnInheritedWidgetOfExactType<_LayoutInheritedWidget>()!

Steps to reproduce

You can reproduce the issue on this repo. You will get the error if you add Layout and then simply try to use context.layout.breakpoint

I think you haven't added the Layout widget anywhere in your app no?
