td_json_client

Description:

td json client

Telegram client for TDLib JSON interface #
td_json_client is a Dart library that provides binding for the TDLib JSON interface via FFI.
It comes with a simple Telegram client and classes for the Telegram API (version 1.8.10).
Because you cannot invoke native callback outside an isolate this library wraps TDLib (libtdjson)
into antoher library (libtdjsonlc). The libtdjson logs are sent to the Dart thread via a SendPort.
Due to the size limitation of packages on pub.dev, the documentation for the TdLib API classes is not generated.
To generate it locally, remove the nodoc options from dartdoc_options.yaml, run dart doc . and
dhttpd --path doc/api and access it at localhost:8080.
