await, how it works?

if I have something like:

var x = await retrieveData()
if (x!= nil){
do stuff
}

where retrieveData() does an http request. The question is: Does the if condition wait for the retrieving data or not? (In a better way, does the if condition always return false or not?)

Yes, the if condition "waits". The code only continues to execute after the Future returned from retrieveData completed.

Without async/await it would be

return retrieveData().then((x) {
  if(x!= null) {
    do stuff
  }
})
