screen reader for support dart pad

[adil-s]

Hi there! I've just tried out dart pad and it is not accessible for screen reader user. when I press enter on multi line edit box, the screen reader says"blank". I'm sure that there is code in edit box because if I try selecting and copying of code and then pasting the code in to empty text file, I'm able to paste it. the most accessible web editor for screen reader is Monaco Editor. I would be truly grateful if you could embed the Monaco Editor in to dart pad or let me switch between default dart pad and Monaco editor based dart pad. Monaco editor link: https://microsoft.github.io/monaco-editor/index.html OS: windows 10 browser: chrome screen reader: NVDA

steps to reproduce the issue:

1. turn on the screen reader and open the dart pad
2. type something in edit box and try reading it using arrow keys .
