I can set proxy with default httpClientAdapter.
But with dio_http2_adapter, cannot set proxy.
Anyone know how to set proxy with dio_http2_adapter?

No, you can't set proxy with this implementation of dio_http 2_adapter.
The reason is that dart http 1 client implement tunnel proxy out of box, http2 dont.
You can write your own implementation of Connection Manager that support tunnel connection.
Example is here: dart-lang/http#1360

To get proxy host and port you need to ask system like this in android: System.getProperty("http.proxyHost"), System.getProperty("http.proxyPort")
