Getting started

To use base functionalities just set up navigation to devtools screen

Navigator.of(context).push(MaterialPageRoute(
                        builder: (context) => const DevtoolsMenuScreen()));

To use MaterialApp tools add these lines to your MaterialApp constructor

showPerformanceOverlay: DebugOptions.performanceOverlay.object.optionValue,

checkerboardOffscreenLayers: DebugOptions.offscreenLayers.object.optionValue,

checkerboardRasterCacheImages:DebugOptions.rasterCacheImages.object.optionValue,

debugShowMaterialGrid: DebugOptions.materialGrid.object.optionValue,

showSemanticsDebugger: DebugOptions.semanticsDebugger.object.optionValue,

REMEMBER THAT DEBUG FEATURES CAN ONLY BE USED IN DEBUG MODE - RELEASE MODE FUNCTIONALITIES DIFFER
