+## 0.0.10
+
+- One little 'Y' I missed
+- Fixed out of range error with `_adjustSelection`
+
+## 0.0.9
+
+- Drastically improved usability and performance with flutter web and canvaskit renderer, especially on mobile
+- Using streams to more accurately call `widget.onValidCardDetails` when the card details are valid and completed
+- Added `cursorColor` customization

+
+## 0.0.8
+
+- Updated dart sdk constraints again... oops (>=3.0.0)
+
+## 0.0.7
+
+- Changed pubspec versioning to allow lower SDK constraints (>=2.12.0)
+
+## 0.0.6
+
+- Improved assertion and error messaging when missing stripe implements
+- Added better doc comments
+- Fixed `CardTextField.delayToShowLoading`, now it uses it
+- Fixed bad assertion logic when providing stripe keys
+- Added ability to make Stripe call with `GlobalKey`
+- Refactored method `onTokenReceived` to `onStripeResponse` to be clearer
+- Refactored method `onCardDetailsComplete` to `onValidCardDetails` to be clearer
+
+## 0.0.5
+
+- Fix Web, invalid call to `Platform.isAndroid`
+- Analysis issues fixed for pub points
+
+## 0.0.4
+
+- Fix for focus and soft keyboard on mobile devices

+
+Lots of improvements!
+
+- `CardTextField` now has customizable styles. Stripe integration is natively handled now, returning a card token, if stripe keys are provided.
+- `README` revamped with emojis, screen recordings, the whole nine yards.
+- `LICENSE` changed from BSD-3.0 to MIT license for pub points, I guess it wasn't being recognized correctly...
+- Added `http` depency for handling Stripe token api call.
+- Added Widget tests because that should be a thing that gets checked.
+- Fix for backspacing on mobile not changing focus.
+- Fix for text field spacing when in small form factor
+- Much improved usability on mobile, added manually scrolling to element
+- Added Icon Size param for card Provider Icon

 A simple and clean Stripe Element Card clone, rebuilt in native Flutter widgets.
 
+# DISCLAIMER
+
 This is not an officially maintained package by Stripe, but using the html stripe
-elements they provide with flutter is less than ideal.
+elements they provide in flutter was inconvenient for me, so I made this package.
 
-## Features
+# Features
 
-- Card number validation
+Got to use emojis and taglines for attention grabbing and algorithm hacking:
-- No more depending on Flutter Webview
 
-## Getting started
+- ⚡ Blazingly fast ( its as fast as the rest of flutter )
+- 🧹 Cleaner & Easier to Use ( fewer dependencies than the official stripe elements )
+- 🛡  Safe and Supports all Flutter Targets ( its native flutter with minimal dependencies )
+- ☑  Seemless UI/UX ( hard to match stripe quality, but I think I got pretty close )
+- 💳 Built-in Stripe Integration ( guess that one is obvious )
+- ☯  Chi Energy Boost ( alright I'm fishing... )
+
+## Why StripeNativeCardField?
+
+- Fewer dependencies: no more depending on Flutter Webview
+- Customizable: the entire field can inherit native Flutter styling, i.e. `BoxDecoration()`
+- Native Implementation: compiles and loads like the rest of your app, unlike embeded html
+- Automatic validation: no `inputFormatters` or `RegExp` needed on your side
+
+The card data can either be retrieved with the `onValidCardDetails` callback, or
+you can have the element automatically create a Stripe card token when the fields
+are filled out, and return the token with the `onTokenReceived` callback.
+

+This dark mode style example provided [here](https://git.fosscat.com/n8r/stripe_native_card_field/raw/branch/main/example/lib/dark_customization.dart)
+
+For documentation on all of the available customizable aspects of the `CardTextField`, go
+to the [API docs here](https://pub.dev/documentation/stripe_native_card_field/latest/stripe_native_card_field/CardTextField-class.html).
+
+### Smooth UX
+
+![Smooth UX](https://git.fosscat.com/n8r/stripe_native_card_field/raw/branch/main/readme_assets/smooth_ux.gif)
+
+Mimics the Stripe html elements behavior wherever possible. Auto focusing / transitioning text fields, backspacing focuses to last field,
+automatically validating user input, etc.
+
+# Getting started
 
 - Install the package by running `flutter pub add stripe_native_card_field`
 
@@ -19,20 +57,47 @@ elements they provide with flutter is less than ideal.
 
 Include the package in a file:
 
+
 ```dart
 import 'package:stripe_native_card_field/stripe_native_card_field.dart';
 ```
 
+### For Raw Card Data
+
+Provide a callback for the `CardTextField` to return you the data when its complete.
 ```dart
 CardTextField(
   width: 500,
-  onCardDetailsComplete: (details) {
+  onValidCardDetails: (details) {
     // Save the card details to use with your call to Stripe, or whoever
     setState(() => _cardDetails = details);
   },
 );
 ```
 
-## Additional information
+### For Stripe Token
+
+Simply provide a function for the `onStripeResponse` callback!
+
+```dart
+CardTextField(
+  width: 500,
+  stripePublishableKey: 'pk_test_abc123', // Your stripe key here
+  onStripeResponse: (Map<String, dynamic> data) {
+    // Save the stripe token to send to your backend
+    setState(() => _tokenData = data);
+  },
+);
+```
+
+If you want more fine-grained control of when the stripe call is made, you
+can create a `GlobalKey` and access the `CardTextFieldState`, calling the
+`getStripeResponse()` function yourself. See the provided [example](https://pub.dev/packages/stripe_native_card_field/example)
+for details. If you choose this route, do not provide an `onStripeResponse` callback, or you will end up
+making two calls to stripe!

-# Steps to Publish
-
-1. Initialize Library
-2. Write Library
-4. Write some tests
-5. Publish!
-
----
-
-# 1. Initialize Your Library!
-
----
-
-## Publishing Requirements
-
-- You must include a LICENSE file.
-- Your package must be smaller than 100 MB after gzip compression.
-- Your package should depend only on hosted dependencies (from the default pub
-package server) and SDK dependencies (sdk: flutter).
-- You must have a Google Account,
-
----
-
-## Publishing is Forever
-
-To make sure projects don't break after using a dependency, you are unable to
-take down a published project.
-
-If you will have regrets publishing, turn back now.
-
----
-
-## Initialize Project
-
-Creating a flutter library is straightforward, simply run the command
-
-```sh
-flutter create -template=package <package_name>
-```
-
-Creates a new flutter project with a simple example library inside.
-
----
-
-## Select License
-
-This is important. The dart team recommends the BSD-3 clause license.
-
----
-
-## pubspec.yaml Considerations
-
-In the `pubspec.yaml` file, it is recommended to include a "homepage" or "repository"
-field. This gets popultated into the package page on [pub.dev](https://pub.dev).
-
-```yaml
-# Top of pubspec.yaml file
-name: stripe_native_card_field
-description: A native flutter implementation of Stripes Card Field.
-version: 0.0.1
-repository: https://git.fosscat.com/nathananderson98/stripe_native_card_field
-```
-
----
-
-# 2. Write Your Library
-
----
-
-## Important Bits
-
-Be sure to include a `README.md` file at the root of your library as this is
-what determines the content of your packages page on [pub.dev](https://pub.dev)
-
-A `CHANGELOG.md` file can also be included and will fill out a tab on the
-package's page
-
-### Verified Publisher
-
-You can publish under a verified domain as a "Verified Publisher". Its a bit of
-a process. But it adds a cool checkmark on your package and you can hide your email.
-
----
-
-## Tests
-
-Its a good idea to include some Unit Tests and Widget Tests for your library.
-
----
-
-# 3. Publishing!
-
----
-
-## Dry Run
-
-To see the results of what publishing will look like without going through with it run
-
-```sh
-dart pub publish --dry-run
-```
