Looks like you're making a network request from within build() (which you may not want to do, since build is attempting to build the next frame to display) and expects to be returned from immediately.

Regardless, it looks like you're attempting to pass a URI to Uri.parse which it believes is invalid (hence the FormatException).

https://d.apicloud.com/mcm/api/customers?filter={"fields":{"id":true,"uname":true,"uphone":true,"usfz":true},"where":{"ubirthday":{"between":["2017-04-20 09:00:13.155657","2017-04-24 09:00:13.155657"]}},"order":"updatedAt Desc,createdAt Desc","skip":0,"limit":10}

It looks like it's the space in "updatedAt Desc" which is invalid. Try wrapping in Uri.encodeFull:

Uri.parse(Uri.encodeFull('https://d.apicloud.com/mcm/api/customers?filter={"fields":{"id":true,"uname":true,"uphone":true,"usfz":true},"where":{"ubirthday":{"between":["2017-04-20 09:00:13.155657","2017-04-24 09:00:13.155657"]}},"order":"updatedAt Desc,createdAt Desc","skip":0,"limit":10}'));

Actually turns out the [ ] are also not valid Uri characters it's just I thought they were since browsers are so forgiving about them. :)

Looks like it's actually possibly a conformance bug in Dart's Uri parser and I've filed dart-lang/sdk#29420 to track. You can workaround by encoding before parsing.
