Currently it is not possible to detect if a TextPosition is located at a soft word wrap. We should provide an API, most likely through RenderEditable that gives this information. This is necessary to accomplish the use case below.

Use case

On iOS we want to be able to toggle the toolbar if we tap on the same TextPosition regardless of the TextAffinity when our tap is not at a soft word wrap. When our tap is at a soft word wrap we want to hide the toolbar if the TextAffinity has changed and toggle the toolbar if it hasn't.

Proposal

Provide an API through RenderEditable that tells us if a given TextPosition is located at a word wrap.
