Sorry for the late response.
Is this still an issue with recent Flutter versions?

[dbenninger]

Yes, I can confirm this is still an issue with flutter v0.5.1

[polenchheang]

Hi @zoechi, sorry for late reply. Issue is still happen on Flutter 0.7.3-pre.26 • channel master .
Note: that you need to rebuild the App after you add enableFlutterDriverExtension(); to see the issue.

[zoechi]

@polenchheang thanks a lot for the update.

[ROTGP]

I just lost hours on this. It essentially blocks me from implementing integration testing on a package I'm developing. Can anyone suggest a temporary workaround?

[weixfeng]

I also just spent a few hours on this issue. Hi @zoechi, this is a blocking issue for us. Do you have any workaround or ETA on the fix?

[ROTGP]

@zoechi any progress regarding this issue? It's been open for 9 months and seems to be a blocker. Not being able to perform integration testing essentially prevents us from releasing our app. I'm on Flutter v1.0.0 (stable channel) and the issue as described by @polenchheang continues to exist. After enableFlutterDriverExtension() is called, the keyboard refuses to appear and no text can be entered into the textfield.
