在Flutter中更新StreamController内部的TextFormField

Question

Inside a StreamBuilder, I try to display a TextFormField with a value coming from a REST API.

The stream is triggered and hasData is true

Issue is that the value inside the TextFormField is not updated from the data coming from the stream.

I have tested 2 methods:

• setting initialValue with value coming from the stream

• using a textController (set as a class property) and use .text()

In both cases, the value is not updated

Answer 1

经过一段时间的测试，它可以与textController解决方案一起使用。
