cursor position error after dynamic insert

[li-xiaoyin]

My requirement is when user tap enter then auto insert two space. and my code as follows.
when I auto insert space, I expect cursor appear after space but now it appear before space
May be my code is wrong. please give me some suggestion Thank you.

I wish you can provide more examples.

@OverRide
void initState() {
this._controller.addListener(() {
this._controller.changes.first.then((value) {
if (value.item2.length >= 2 &&
value.item2[1].isInsert &&
value.item2[1].data == "\n") {
final index = this._controller.selection.baseOffset;
this._controller.document.insert(index, "　　");
}
});
});
}

I guess you can follow https://github.com/singerdmx/flutter-quill/blob/master/lib/widgets/editor.dart#L376 to do something similar

Tapping on image or url is what we have.
You can create a pull request so that you can pass in additional behavior if you want.

check https://github.com/singerdmx/flutter-quill/blob/master/lib/widgets/editor.dart#L340

getEditor().widget.onLaunchUrl can be passed from outside
I think you can do sth similar

Would you mean that I need to change the editor.dart to implements my requirement？ OK I will try to do this and I think have an extension function to implements custom requirement is a better way.

Yes you can submit a pull request for external extensibility on tapping.

_createIndent() {
final indent = "　　"; // em space
final index = this._controller.selection.baseOffset;

this._controller.updateSelection(
TextSelection.collapsed(offset: index + 2), ChangeSource.LOCAL);
