I want to programmatically paste a string into a text field or text view at the current caret position.
Is there an easy way to do this? I would need to know the current caret position, but there's no method to retrieve it, right? Don't want to call private API. Is there any legal way to do it?
Use UITextView's selectedRange method. If the range has a non-zero length (in the case of the user having selected some text), just take the location (or NSMaxRange(), or replace the entire range...)
Instead of pasting option. Get the string from textfield or textview insert the string which you want to paste it by providing the index and then clear the textfield then pass the string which you inserted.

I want to fill a textView with a string, after a click on a button.
I did every thing correctly but it shows only the "a" character and the other with a fallback character.

You should use Unicode::strncpy() instead of snprintf()
Hey I have a TextField and a controller for it through which I access its current text value and add some text like (Some Special Asterix or text with angular brackets just like hashnode's text editor) to it when needed, adding text at the end is easy.
controller.text += "Something";
The above code will add Something to the end. But I need to know the current TextFields Cursor position and add text according to it.
I really love to know how we can do it in flutter efficiently
Try this to get the cursor position
print(controller.selection.baseOffset);
print(controller.selection.extentOffset);
if they are the same, it is current cursor position.
if not, it means that some of text is selected, baseOffset is start position and extentOffset is end positon.
So I am using selectedTextRange to get a cursor position from my UITextField. I would like to obtain a substring from the beginning of my TextField text up to the cursor position. How would I go about doing this? I am able to create the UITextRange I want but I don't know how to use this to get the actual substring since substringWithRange seems to only work with NSRange. Any guidance would be greatly appreciated.
You need to use the methods from the UITextInput protocol, which is implemented by all text views, to do this. With a text range, you can simply call textInRange: to get the text.
To get the text from the beginning of the field up to the selected position, you'll need to make a text range first with textRangeFromPosition:toPosition:, passing beginningOfDocument for the first argument, and the start of your text range for the second argument.
I am making an application in which i have use a keyboard for input in text field. Now my client requirement is that he need a substitute of keyboard input for text field. Basically i have need increment and decrement value of text field. SO i need some other function which is used for increment and decrement value of text field. For that i have use keyboard and now i require any other function like increment and decrement operator or tap to increment and decrement text or any thing else. What i used for that purpose?
Thanks in advances...
Put a pair of up/down buttons next to the text field. UIButtons will still work when the keyboard is visible. You can also hide these buttons when they aren't needed.
I have a UITextField which I created programmatically. This text field is used to input a time. The placeholder text is "00:00:00.000". When the text field is tapped, a number pad will appear. Ideally, I want the gray place holder text to remain as the user types. As they enter a number, it replaces the gray zeros in the place holder text and skips over the colons and period (leaving the format intact without the user entering any punctuation). If it is not possible to keep the place holder text and replace it as the user types, I would like the punctuation to automatically be entered.
Thanks in advance!
iOS has a UIDatePicker control for this, if you want to go the way you are going then you will have handle all the user input your self.
