What?

Support for null-safety dart code.

Why?

Because the package is not working in a project with null-safety.

How?

• running dart migrate in both the package directory and the example project directory.
• allowing null for some variables.

Anything Else?

The package is currently not working for projects that use dart 2.12.0 with null-safety enabled, It will be very helpful to upgrade it ASAP.

Flutter Icons are not being rendered in release mode. I tried using EvaIcons and here is the code sample for the footerTablet.dart

import 'package:eva_icons_flutter/eva_icons_flutter.dart';
import 'package:flutter/material.dart';
import 'package:portfolio/functions/yearFinder.dart';
import 'package:portfolio/globals/myColors.dart';
import 'package:portfolio/globals/myDimens.dart';
import 'package:portfolio/globals/mySpaces.dart';
import 'package:portfolio/globals/myString.dart';

class FooterTablet extends StatefulWidget {
  _FooterTabletState createState() => _FooterTabletState();
}

class _FooterTabletState extends State<FooterTablet> {
  @override
  Widget build(BuildContext context) {
    return Container(
      height: MyDimens.double_150,
      color: MyColors.white,
      child: Padding(
        padding: const EdgeInsets.symmetric(horizontal: MyDimens.double_50),
        child: Column(
          crossAxisAlignment: CrossAxisAlignment.start,

Error Reproduce

Error: Cannot run with sound null safety, because the following dependencies don't support null safety:

• package:fleva_icons

For solutions, see https://dart.dev/go/unsound-null-safety

Unhandled exception: Bad state: Unsupported Null Safety mode NonNullableByDefaultCompiledMode.Invalid, in null.
