Dart SDK version 2.17.1 does not work

[sugoibtc]

~/sentrify/packages/znn_sdk_dart# cd ../..
~/sentrify# dart pub get

Gives the following error:
"The current Dart SDK version is 2.17.1.

Because every version of znn_sdk_dart from path depends on stream_channel >=2.1.2 which requires SDK version >=2.19.0 <3.0.0, znn_sdk_dart from path is forbidden. So, because sentrify depends on znn_sdk_dart from path, version solving failed."

Installing Dart SDK version 2.19.6 instead, fixes this.
