of the NOTICE file are for informational purposes only and
do not modify the License. You may add Your own attribution
notices within Derivative Works that You distribute, alongside
or as an addendum to the NOTICE text from the Work, provided
that such additional attribution notices cannot be construed
as modifying the License.
You may add Your own copyright statement to Your modifications and
may provide additional or different license terms and conditions
for use, reproduction, or distribution of Your modifications, or
for any such Derivative Works as a whole, provided Your use,
reproduction, and distribution of the Work otherwise complies with
the conditions stated in this License.
5. Submission of Contributions. Unless You explicitly state otherwise,
any Contribution intentionally submitted for inclusion in the Work
by You to the Licensor shall be under the terms and conditions of

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only

# 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 is used as CFBundleVersion.
# Read more about iOS versioning at
# https://developer.apple.com/library/archive/documentation/General/Reference/InfoPlistKeyReference/Articles/CoreFoundationKeys.html
# In Windows, build-name is used as the major, minor, and patch parts
# of the product and file versions while build-number is used as the build suffix.
version: 1.0.0+1
environment:
sdk: '>=3.4.0 <4.0.0'
# 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`.
dependencies:
flutter:
sdk: flutter
path_provider: ^2.1.3
path:
sherpa_onnx:
# When depending on this package from a real application you should use:
# sherpa_onnx: ^x.y.z
# See https://dart.dev/tools/pub/dependencies#version-constraints
# The example app is bundled with the plugin so we use a path dependency on
# the parent directory to use the current plugin's version.

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

# rules and activating additional ones.

# To add assets to your application, add an assets section, like this:
assets:
- assets/
- assets/sr-data/enroll/
- assets/sr-data/test/
# - 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

# Usage
## macOS
1. Build required libraries
```bash
git clone https://github.com/k2-fsa/sherpa-onnx
cd sherpa-onnx
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX=./install -DBUILD_SHARED_LIBS=ON -DCMAKE_OSX_ARCHITECTURES="x86_64;arm64" ..
make install
cd ../sherpa-onnx/flutter/
cp -v ../../build/install/lib/lib* ./macos/
```
2. Test for speaker identification
```bash
cd sherpa-onnx/sherpa-onnx/flutter/example
mkdir assets
```
## Useful commands
```
flutter pub publish --dry-run
flutter run -d macos
flutter run -d linux
flutter run -d windows
flutter build macos
flutter run --release -d macos
# add platform to an existing project
flutter create --platforms=windows,macos,linux .
dart analyze
```

# The following section is specific to Flutter packages.
flutter:
# This section identifies this Flutter project as a plugin project.
# The 'pluginClass' specifies the class (in Java, Kotlin, Swift, Objective-C, etc.)
# which should be registered in the plugin registry. This is required for
# using method channels.
# The Android 'package' specifies package in which the registered class is.
# This is required for using method channels on Android.
# The 'ffiPlugin' specifies that native code should be built and bundled.
# This is required for using `dart:ffi`.
# All these are used by the tooling to maintain consistency when
# adding or updating assets for this project.
#
# Please refer to README.md for a detailed explanation.
plugin:
platforms:
macos:
ffiPlugin: true
# To add assets to your plugin package, add an assets section, like this:
# assets:
# - images/a_dot_burr.jpeg
# - images/a_dot_ham.jpeg
#
# For details regarding assets in packages, see
# https://flutter.dev/assets-and-images/#from-packages
#
# An image asset can refer to one or more resolution-specific "variants", see
# https://flutter.dev/assets-and-images/#resolution-aware
# To add custom fonts to your plugin package, 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 in packages, see
# https://flutter.dev/custom-fonts/#from-packages
