✨ TextInputFormatters Included

A collection of custom TextInputFormatters designed to enhance and control user input in Flutter apps.

🔠 Typing Delay Formatter

Mimics human-like typing latency by preventing direct typing and simulating delayed character-by-character input.

/// Example:
TypingDelayController typingController = TypingDelayController();

TextField(
  controller: typingController,
  onChanged: (value) {
    if (!typingController.text.endsWith(value.characters.last)) {
      typingController.typeCharacter(value.characters.last);
    }
  },
)

---

🔢 Digits Only Formatter

Allows only numeric digits (0–9).

/// Example:
TextField(
  inputFormatters: [DigitsOnlyFormatter()],
)

---

🔁 Input Mirror Formatter

Reverses the text in real-time as the user types.

/// Example:
TextField(
  inputFormatters: [InputMirrorFormatter()],
)

Input: hello → Displayed: olleh

---

🚫 Prevent Repeat Characters

Blocks repeated characters (e.g., aa → a).

/// Example:
TextField(
  inputFormatters: [PreventRepeatCharactersFormatter()],
)

---

✂️ Block Clipboard Access

Disables pasting text into the field via the clipboard.

/// Example:
TextField(
  inputFormatters: [BlockClipboardFormatter()],
)

---

🪞 Only Palindromes Allowed

/// Example:
TextField(
  inputFormatters: [PalindromeOnlyFormatter()],
)

Allowed Input: madam, racecar
Blocked Input: hello, world

---

🔡 Only Alphabets

Removes digits and symbols, allowing only alphabetic input.

/// Example:
TextField(
  inputFormatters: [OnlyAlphabetsFormatter()],
)
