[Android] TMP_InputField throws an exception upon Submit

--

-

see: https://unity.slack.com/archives/C06TQC5TK/p1685380002972049

 

Editing a textfield on Android and then submitting throws an exception.

Steps:
1. Create a scene with a Canvas
2. Add a TMPro Input field
3. Run the app on an Android device
4. Once the app is running on the device, focus the input field and enter some text
5. Submit

A quick investigation shows that eventData is null when TMP_InputField.OnSubmit is called.
Here is the stack

/Unity: NullReferenceException: Object reference not set to an instance of an object.
at TMPro.TMP_InputField.OnSubmit (UnityEngine.EventSystems.BaseEventData eventData) [0x0003f] in ./Library/PackageCache/com.unity.ugui@2.0.0/Runtime/TMP/TMP_InputField.cs:4438
at TMPro.TMP_InputField.LateUpdate () [0x002cb] in ./Library/PackageCache/com.unity.ugui@2.0.0/Runtime/TMP/TMP_InputField.cs:1747

    I have a small game and it has thousands crashes. A big game is probably having millions of these crashes and they are still "under consideration", this is ridiculous...

    TMPro 3.2.0-pre.6 has this issue as well.
    It's a little bit stupid that OnSubmit is calling the Use() method of the eventData without checking whether the eventData is null.
    There are multiple places where OnSubmit is being called with null.
    Simple fix is to null check.

    Does Unity not have possible null reference analysis on their code?
    It would've been easily prevented.

    Happens on iOS as well.
