First of all: awesome work ✨

I think it would be super awesome and beneficial if you made this whole thing be a package that you can upload to https://pub.dev/ and let other people work with it ❤

Certainly willing to contribute as well!

Describe the bug
When I press any button on the mathkeyboard nothing occurs on the display but following error is thrown:

JavaScript string was: 'addCmd('9', {isOperator: false})' Error Domain=WKErrorDomain Code=4 "A JavaScript exception occurred" UserInfo={WKJavaScriptExceptionLineNumber=1, WKJavaScriptExceptionMessage=ReferenceError: Can't find variable: addCmd, WKJavaScriptExceptionColumnNumber=7, WKJavaScriptExceptionSourceURL=about:blank, NSLocalizedDescription=A JavaScript exception occurred}

To Reproduce
Steps to reproduce the behavior:
Just start the App (in my case iPhone Simulator 11 Pro Max - iOS 13.3) and try to type any kind of Input with the mathkeyboard.

Expected behavior
A clear and concise description of what you expected to happen.

Normally the keyboard expression should appear in the WebView.

Version:

• iPhone Simulator 11 Pro Max - iOS 13.3

The font looks weird.

The description says it is completely offline yet when installed it needs internet permission.... something is not right here.

If the reason for internet access is that it is trying to look up currency conversion factors, shouldn't the "completely offline" description be changed?

But then, I can't find how to do any sort of unit conversions in this app... is there some other reason for internet access?

The following line prevents the package from being accidentally published to

pub.dev using flutter pub publish. This is preferred for private packages.

publish_to: 'none' # Remove this line if you wish to publish to pub.dev

The following defines the version and build number for your application.

A version number is three numbers separated by dots, like 1.2.43

followed by an optional build number separated by a +.

Both the version and the builder number may be overridden in flutter

build by specifying --build-name and --build-number, respectively.

In Android, build-name is used as versionName while build-number used as versionCode.

Read more about Android versioning at https://developer.android.com/studio/publish/versioning

In iOS, build-name is used as CFBundleShortVersionString while build-number used as CFBundleVersion.

Dependencies specify other packages that your package needs in order to work.

To automatically upgrade your package dependencies to the latest versions

consider running flutter pub upgrade --major-versions. Alternatively,

dependencies can be manually updated by changing the version numbers below to

the latest version available on pub.dev. To see which dependencies have newer

versions available, run flutter pub outdated.

The "flutter_lints" package below contains a set of recommended lints to

encourage good coding practices. The lint set provided by the package is

activated in the analysis_options.yaml file located at the root of your

package. See that file for information about deactivating specific lint

rules and activating additional ones.

flutter_lints: ^1.0.0

For information on the generic Dart part of this file, see the

following page: https://dart.dev/tools/pub/pubspec

The following section is specific to Flutter.

flutter:

The following line ensures that the Material Icons font is

included with your application, so that you can use the icons in

the material Icons class.

uses-material-design: true

To add assets to your application, add an assets section, like this:

assets:

• assets/html/

assets:

- images/a_dot_burr.jpeg

- images/a_dot_ham.jpeg

An image asset can refer to one or more resolution-specific "variants", see

https://flutter.dev/assets-and-images/#resolution-aware.

For details regarding adding assets from package dependencies, see

https://flutter.dev/assets-and-images/#from-packages

To add custom fonts to your application, add a fonts section here,

in this "flutter" section. Each entry in this list should have a

"family" key with the font family name, and a "fonts" key with a

list giving the asset and other descriptors for the font. For

example:

fonts:

- family: Schyler

fonts:

- asset: fonts/Schyler-Regular.ttf

- asset: fonts/Schyler-Italic.ttf

style: italic

- family: Trajan Pro

fonts:

- asset: fonts/TrajanPro.ttf

- asset: fonts/TrajanPro_Bold.ttf

weight: 700

For details regarding fonts from package dependencies,

see https://flutter.dev/custom-fonts/#from-packages

Hi,
First of all I wanted to say thank you for having developed such a clean and efficient calculator with scientific operations, I do use it a lot.

I see that you are planning to implement it and I think one way to do it would be to have a scrollable list of the past calculations where you could call them again and edit them by tapping on the item in the list.
It could be very handy for calculations of the same formula with different input parameters.
