Subject: [PATCH] flutter_tool: remove explicit length header in HTTP response
 (#119869)

This is already handled by pkg:shelf
There is some subtlety with String here, since String.length might not
align with the size in bytes over the wire, depending on the contents
and the encoding

Best to just let pkg:shelf handle it
