描述
Description
The order remains constant for almost every circumstance:
onChange -> onChangeText -> onSelectionChange
Here are some cases that i discovered in iOS (could be more)
- For the multiline textinput, for the first keypress onSelectionChange fires first, but for later key presses onChangeText/onChange fire first
- Selecting and deleting a word also deletes a space to the left of it, but in this case onSelectionChange fires first
Steps to reproduce
Snack
In textInput component, use multiline and console.log as callbacks for each of the functions in discussion, see the output
