Ever wondered why your custom slider doesn't register all taps? Or maybe it seems you can tap everywhere, even though your button should be much smaller?
package:debug_hit_points renders a dot matrix on top of your Widget, displaying exactly where hit tests succeed.

Features

• Can be wrapped around any Box widget
• Per default disabled in non-debug builds
• Point grid resolution, color and point size can be customized
• Try different HitTestBehavior modes

Getting started

In your pubspec.yaml add:

dependencies:
  debug_hit_points: ^1.0.0

or run

flutter pub add debug_hit_points

Usage

Import the package

import 'package:debug_hit_points/debug_hit_points.dart';

And wrap your widget with DebugHitPoints

Scaffold(
  body: DebugHitPoints(
    color: Colors.red,
    resolution: 10,
    child: FlutterLogo(),
  ),
)
