knowa_sdk 2.0.0

Code push for Flutter on the stock Flutter SDK: ship a Dart fix to apps already installed, signed with your own key, with no forked engine.

example/main.dart

// A Flutter app wired to Knowa.
//
// In a real app `knowa init` generates the three constants below into
// lib/knowa_config.dart, from the keys it creates, and `knowa release` fills
// in knowaAppBridges while it builds. They are spelled out here so this file
// stands alone.
