inspector

A Flutter package for inspecting widgets. Also comes with an eyedropper and a magnifying glass. Useful for debugging widgets and for QA testing.

Supports keyboard shortcuts if you're using a physical keyboard.

Inspired by inspx.

WIP

Warning, the development of this package is still in progress and some things may break your app.

Features

• x Color picker
• x Size inspection
• x Padding inspection
• x Keyboard shortcuts
• x Zooming
• x BorderRadius inspection
• x TextStyle inspection

Installing

Add the dependency:

$ flutter pub add inspector

Import the package:

import 'package:inspector/inspector.dart';

Wrap MaterialApp.builder or WidgetsApp.builder with Inspector:

MaterialApp(
  home: ExampleApp(),
  builder: (context, child) => Inspector(child: child!), // Wrap [child] with [Inspector]
),

Optionally, you can pass isEnabled to the Inspector to disable it. By default, the inspector is disabled when kReleaseMode == true.

Usage

If the inspector is enabled, then a panel appears on the right side of the screen, with buttons to toggle size inspection and the color picker.

It's quite straightforward to use, just tap on the widget that you want to measure or tap on the pixel to get its color.

You can also use keyboard shortcuts - Shift will toggle the color picker, Z will toggle the zoom, and Alt or Cmd will toggle the widget inspector.

Custom inspectors

You can check out the example at custom_inspector_example.dart to see how to build your own custom inspector UI by using the InspectorController.
