Want to use TextField inside a Streambuilder in flutter? In order to use a StreamBuilder correctly you must ensure that the stream you are using is cached on a State object. While StreamBuilder can correctly handle getting new events from a stream, receiving an entirely new Stream will force it to completely rebuild. In your case, getClientProfile().snapshots() will create an entirely new Stream when it is called, destroying all of the state of your text fields.
