dr_libphonenumber

A Flutter plugin that uses FFI to access libphonenumber.

Getting started

Android

This plugin works out of the box.

iOS

• The static library will be stripped in release mode. Follow this to prevent.
• This library does not support armv7 and armv7s. Therefore, you need to configure the build target to support only arm64.
  1. Open iOS project in XCode.
  2. Go to Target Runner > Build Settings > Architectures
  3. Set the Architectures from Standard Architectures (arm64, armv7) to arm64.

Feature request

This plugin does not support all the features from the Google libphonenumber. You can file an issue and I will work on it. Alternatively, you can also create a PR to contribute.
