• When there is an initialValue, Backspace doesn't do anything until you type other characters.
• When there are multiple Inputs, all of them are considered active at the same time. There's probably an internal error, since after the first letter is typed, the inputs all stop responding. (Interestingly, Android must keep an internal buffer of what's being typed since its autocomplete carries on without concern.)
• I cannot choose to get or lose focus.
• Keyboard's Enter/Return doesn't look like it does anything, and Input doesn't have an optional parameter callback for the Enter/Return case.

(As mentioned in other issues, it would also be nice to manipulate the cursor position and selection. #151 and #152)

I've found some more bugs

• I can't type any digits when using the standard KeyboardType.TEXT.
• When Android autocomplete spits out a word, if you press backspace repeatedly then the Input's internal text buffer seems to get confused. (This works when there is an initialValue)

For the latter one, the example is the placeholder 1106332964. I typed some random characters. And then swiped a lot on my keyboard (which completed to the word judiciously). After that, I tapped backspace, which after a few times ended up messing up the Input.

I/sky     (12189): Updating color with 1106332964h

I cannot choose to get or lose focus.

The Input widget has an autofocus argument now that you can use to grab focus if no one else has it. To get focus, you can call Focus.moveTo with the key you want to focus.

Losing focus is #1308

[abarth]

Focus.clear now exists.

Keyboard's Enter/Return doesn't look like it does anything, and Input doesn't have an optional parameter callback for the Enter/Return case.

We now call the onSubmitted callback for Input when the user taps Enter/Return.

I think I've fixed all the issues in this bug. Please let me know if you're still having trouble.
