Following up on an old To-Do regarding cursorColor:

The Material spec doesn't provide specific guidance about the cursor color and the examples aren't entirely consistent - https://material.io/components/text-field. In most cases the examples use the primary or error color, depending on the TextField's stat. That said, the default is clearly wrong and shouldn't be specified here. We need a TextFieldTheme per flutter.dev/go/material-theme-system-updates (see "Component Theme Normalization") and, similarly, TextField should be responsible for computing the default cursor color.
