sse 3.1.1

sse: ^3.1.1 copied to clipboard

• Make isInKeepAlive on SseConnection private.

Note that this is a breaking change but in actuality no one should be depending on this API.

• Add optional keepAlive parameter to the SseHandler. If keepAlive is supplied, the connection will remain active for this period after a disconnect and can be reconnected transparently. If there is no reconnect within that period, the connection will be closed normally.

• Add retry logic.

Possible Breaking Change Error messages may now be delayed up to 5 seconds in the client.

• Remove package:http dependency.

• Use proper headers delimiter.

• Support Firefox.

• Fix an issue where messages could come out of order.

• Support the latest package:stream_channel.
• Require Dart SDK >=2.1.0 <3.0.0.

• Update to package:uuid version 2.0.

• No longer expose close and onClose on an SseConnection. This is simply handled by the underlying stream / sink.
• Fix a bug where resources of the SseConnection were not properly closed.

• Internal cleanup.

• Initial commit.
