Having issues cropping a widget with out an image
All I get is a blank screen. Here is a minimal example.
` import 'package:crop/crop.dart'; import 'package:flutter/material.dart';
class CropView extends StatelessWidget {
final controller = CropController(aspectRatio: 1 / 1);
@override Widget build(BuildContext context) { return Crop( controller: controller, child: Container(width: double.infinity, height: double.infinity, color: Colors.purple,), ); } } `
If instead of a container I use an image then it works fine but I need to crop widgets. That's why I chose this library.
