This is devtools package. Use flutter devtools on the go. Just install debug app version and enjoy all the helpful tools to inspect your app

Features

All you could do with IDE of your choice- always with you:

• Slowing animations
• Highlight repaints
• Inspect oversized images
• Show guidelines
• Disable opacity layers
• Paint layer borders
• and more...

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.debugValue,

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

Roadmap

• architecture overhaul (current file structure is still a mess)
• live logcat view (Android only)
• translations (?)
• network call hijacker - monitor all your app's network calls in one place
• more tools based on feedback
