An example of using an svg pattern as a background with the help of Flutter Shape Maker

	// so it doesn't conflict with Image from material package
	import 'dart:ui' as ui;

	import 'package:flutter/material.dart';

	// svg from hero patterns (I Like Food): https://www.heropatterns.com/
	// converted to CustomPainter code using: https://fluttershapemaker.com/

a workaround for keeping haura_connect subscriptions alive when using JWT

	import 'dart:async';
	import 'package:meta/meta.dart';
	import 'package:hasura_connect/hasura_connect.dart';
	import 'package:http/http.dart' as http;

	// problem:
	// when subscribing to`HasuraConnect.subscription`, a websocket connection is created on the first subscription
	// call. The websocket connection is created only once with the initial subscription and the provided TokenInterceptor
	// or headers. When the token expires during an active subscription, HasuraConnect doesn't stop the subscription, or try
	// to reconnect with the latest token in in the TokenInterceptor nor does it throw an error. It'll keep calling `onRequest`

lost microseconds with DateTime.parse or DateTime.fromMicrosecondsSinceEpoch

	// Based on Flutter 1.26.0-17.3.pre Dart SDK 2.10.4
	// filed issue at https://github.com/dart-lang/sdk/issues/44876
	main() {
	final datetimeParsed = DateTime.parse('2021-02-05T22:37:12.933232+00:00');
	final datetimeMS = DateTime.fromMicrosecondsSinceEpoch(1612564632933232);

	print(datetimeParsed.toIso8601String()); // prints 2021-02-05T22:37:12.933Z
	print(datetimeMS.toUtc().toIso8601String()); // prints 2021-02-05T22:37:12.933Z

	print(datetimeParsed.microsecondsSinceEpoch); // prints 1612564632933000
