VxTextfield error on clear

[chrislaurie-io]

Describe the bug
When I press the clear icon (the x on the right)

To Reproduce
Steps to reproduce the behavior:
1.Create a VxTextField
2. Enter a value
3. Click on the x

Expected behavior
It should just clear

Smartphone (please complete the following information):

• Device: Pixie 3 emulator
• OS: Android
• Null safe

Additional context
A runtime error is thrown inside the decodeEnvelope of the JSONMethodCodec class in the flutter/dart system. The clear does happen correctly afterwards.
