# This section identifies your Flutter project as a module meant for
# embedding in a native host app. These identifiers should _not_ ordinarily
# be changed after generation - they are used to ensure that the tooling can
# maintain consistency when adding or modifying assets and plugins.
# They also do not have any bearing on your native host application's
# identifiers, which may be completely independent or the same as these.

# deeplink_store_example
A store app that includes three screen, ProductList, ProductDetails, and ProductCategoryList.
This app uses go_router to create routing table for all three screens. It also updates the project
parameters for Android and iOS to support deeplinks.
To learn more, visit <link TBD>.
## Getting Started
This app put a placeholder for Android Intent Filters and iOS Associated Domains. To use this
example, update them with your own web domain.

# form_app
A sample demonstrating different types of forms and best practices.
## Sign In with HTTP
[*lib/src/sign_in_http.dart*](lib/src/sign_in_http.dart)
A sign in form using `package:http` to send a request.
## Form widgets
[*lib/src/form_widgets.dart*](lib/src/form_widgets.dart)
A stylized form that uses widgets like TextField, DatePicker, Slider, Checkbox,
and Switch.
## Autofill
[*lib/src/autofill.dart*](lib/src/autofill.dart)
A form that uses AutofillGroup to auto-fill the users name, email, and address.
In order to use Autofill in a browser, your app needs to be hosted with HTTPS.
If you would like to test locally, you can build the app in release mode
(`flutter run -d chrome --release --web-port=5000`).
Then use [tunnelmole](https://tunnelmole.com/docs), an open source tunneling
tool or [ngrok](https://ngrok.com/), a popular closed source tunneling tool
to create an HTTPS url for your local app (`tmole 5000` or `ngrok http 5000`).
## Validation
[*lib/src/validation.dart*](lib/src/validation.dart)
A form that alerts the user if the data entered is invalid.

# Platform Channel Samples
A sample app which demonstrates how to use `MethodChannel`, `EventChannel`, `BasicMessageChannel` and `MessageCodec` in Flutter.
## Goals
* Demonstrate how to use `MethodChannel` to invoke platform methods.
* Demonstrate how to use `EventChannel` to listen continuous value changes from the platform.
* Demonstrate how to use `BasicMessageChannel` and `MessageCodec` to send messages of different types across the platform.
## The important bits
### [Method Channel demo](./lib/src/method_channel_demo.dart)
Demonstrates how to implement a `MethodChannel` to increment and decrement a
counter.
### [Event Channel demo](./lib/src/event_channel_demo.dart)
Demonstrates how to implement an `EventChannel` to listen to value changes from
the Accelerometer sensor from native side.
### [Platform Image demo](./lib/src/platform_image_demo.dart)
Demonstrates how to implement a `BasicMessageChannel` using
`StandardMessageCodec` to load an image from native asset.
### [Basic Message Channel demo](./lib/src/pet_list_screen.dart)
Demonstrates how to implement `BasicMessageChannel` using `JSONMessageCodec`,
`BinaryCodec` and `StringCodec` to send and receive data about pets.
## Questions/issues
If you have a general question about Platform Channels in Flutter, the
best places to go are:
* [The FlutterDev Google Group](https://groups.google.com/forum/#!forum/flutter-dev)
* [The Flutter Gitter channel](https://gitter.im/flutter/flutter)
* [StackOverflow](https://stackoverflow.com/questions/tagged/flutter)
If you run into an issue with the sample itself, please file an issue [here](https://github.com/flutter/samples/issues).
