Flutter Desktop - focus input fields in the form

I am developing an application for the desktop with Flutter. I had to implement the form with multiple input fields. I really need to make the whole focus flow and I have used the FocusNode class to move from one input field to another. Everything is based on the submit event, so when I hit the Enter button on the keyboard it moves to the next field. It is pretty ok, but I have to change it from Enter key to Tab key which is more natural for the desktop users. Have you got any idea what can I do here to achieve such a result? Is there a way to trigger the submit event by different key (than Enter)?
This bug is for making it easy to bind keys to actions. Once that's complete, one of the intended use cases is to add tab support for form field navigation. There's been a lot of work in that area recently, so I wouldn't recommend putting time into working around this yourself.

Creating Custom Keyboard like emoji

Is it possible to create custom Keyboard in iPhone which can get use by any other application. Similar to the Emoji keyboard. Is it possible to take advantage of the international keyboard feature for the iPhone and create a custom keyboard that can be used over for apps on iPhone?
Any help would be appreciated.
My suggestion is exploit the inputView property of textField. You can create a UIView having buttons on it like the keys in key board, and set action for each buttons. Do actions appropriately for tapping each key.

With iOS 8, Apple has made it possible to create custom keyboard that user can access throughout the device(in other applications also).
Please check Keyboard Extension.
You can create your own custom keyboard using Keyboard extension. You can check a nice tutorial here.

iPhone: A built in way to show the user a simple warning/alert message

I have a custom built sign up component that I would like to enhance. I would like to show error messages before sending the data to the server (like "invalid email") using a built in alert system (other than modal) if possible. Is there any on iOS? Do I have to build one myself? I saw that some apps show a grey rectangle near the bottom of the screen, is that custom built?
Thanks!
Check out this code sample if you want to use Tweetbot style notifications in your application, these are non modal
http://blog.mugunthkumar.com/coding/ios-code-tweetbot-like-alertpanels/
All iOS alerts are modal (for now). You will have to build your own if you want different functionality, but it isn't too difficult. You can put together a little UIView with a label that is normally hidden. Then just set the text and show it when you need to.

iPhone webapp change "Done" button

I'm developing a webapp on the iPhone. When entering text in a textfield, a keyboard pops up. Is there a way to change the wording for the "Done" key or hide it? I know how to change the "return" key, I want to change the blue "Done" key.
Thank you.
This has nothing to do with the web application itself , 'done' button is part of mobile safari user interface...No you can't to this from inside your web-app...
The only way to implement something like this (only for jailbroken devices) , is creating a mobilesubstrate hook for mobilesafari (exported as a dynamic library) , for changing any (possible) attributes of the desired subview...
