• Flexible Text Input: Allows customization of the text field with numerous parameters such as cursorColor, cursorRadius, and more for better UI integration.
• Event Handling: Custom event handling for taps outside the text field, allowing for more interactive forms.
• Styling Options: Extensive styling options with default and customizable text styles and decorations.

• Custom Text Controller: Uses PerfectTextController to enhance control over text editing, focus management, and state updates with support for reactive programming via get.
• Reactive State Management: Leverages Rx variables to reactively manage and observe changes to the text field's content and focus state.
• Advanced Focus Control: Offers methods like selectAll, unfocus, and requestFocus to programmatically control focus and text selection.
• Auto-complete: Supports auto-complete functionality, seamlessly integrated into the PerfectTextField.
• Event Handling: Enhanced event handling capabilities for changes in text and focus, along with custom actions on external taps.

• Customizable Options: Fully customizable autocomplete options that can be styled and handled according to your application's needs.
• Reactive User Input Handling: Dynamically generates suggestions based on user input.
• Keyboard Navigation: Supports keyboard actions for navigating through suggestions.
• Selection Callbacks: Provides callbacks for handling the selection of suggestions.
• Advanced Text Handling: Integrates with custom PerfectTextController for more refined control over text input and focus management.

• Value Constraints: Allows setting minimum and maximum values for the input.
• Decimal Precision: Controls the number of digits allowed after the decimal point.
• Smart Correction: Optionally replaces the last digit if input exceeds the maximum decimal length, ensuring continuous input flow without the need to delete characters manually.
• Flexible Input Handling: Prevents undesired inputs like leading zeros and improperly placed decimal points.

Here is a simple example of how to use PerfectTextField in your Flutter application:

import 'package:flutter/material.dart';
import 'package:perfect_text_field/perfect_text_field.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Perfect TextField Example')),
        body: Center(
          child: PerfectTextField(
            controller: PerfectTextController(
              onTextChange: (text) {
                print("Text changed: $text");
              },
              onFocusChange: (hasFocus) {
                print("Field has focus: $hasFocus");
              },
            ),
            inputFormatters: [
              DecimalNumberFormatter(
                min: 1.0,
                max: 100.0,
                decimalLength: 2,
              )
            ],
            keyboardType: TextInputType.numberWithOptions(decimal: true),
          ),
        ),
      ),
    );
  }
}

import 'package:flutter/material.dart';
import 'package:perfect_raw_autocomplete/perfect_raw_autocomplete.dart';

void main() => runApp(MyApp());

class MyApp extends StatelessWidget {
  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(title: Text('Perfect Raw Autocomplete Example')),
        body: PerfectRawAutocomplete<String>(
          optionsBuilder: (TextEditingValue textEditingValue) {
            // Assume your logic to suggest autocomplete options
            return ['Apple', 'Banana', 'Cherry'].where((String option) {
              return option.contains(textEditingValue.text.toLowerCase());
            });
          },
          fieldViewBuilder: (BuildContext context, PerfectTextController textController, VoidCallback onFieldSubmitted) {
            return TextFormField(
              controller: textController.textController,
              onFieldSubmitted: (String value) => onFieldSubmitted(),
            );
          },
          optionsViewBuilder: (BuildContext context, PerfectAutocompleteOnSelected<String> onSelected, Iterable<String> options, void Function(Size?) onSizeChange) {
            return Material(
              elevation: 4.0,
              child: ListView(
                children: options.map((String option) {
                  return GestureDetector(
                    onTap: () {
                      onSelected(option);
                    },
                    child: ListTile(
                      title: Text(option),

PerfectTextField supports all the parameters of TextFormField plus additional ones specific to its functionality:

• onTapOutside: Callback fired when a tap is detected outside the text field.
• prefixText: Optional text to display as a prefix within the text field.
• hintText: Text that suggests what sort of input the field accepts.
• Additional customization parameters such as cursorColor, cursorRadius, etc.

• optionsBuilder: Define how suggestions are generated based on user input.
• fieldViewBuilder: Build the text field widget for input.
• optionsViewBuilder: Build the widget that displays the suggestions.
• onSelected: A callback that fires when an option is selected, allowing for custom action.

PerfectRawAutocomplete is a robust Flutter package designed for implementing customized autocomplete functionality within your Flutter applications. It leverages the fundamental architecture of Flutter's RawAutocomplete to allow for greater flexibility and customization.

DecimalNumberFormatter provides a TextInputFormatter for handling decimal inputs within text fields. This formatter not only enforces numeric constraints but also manages decimal precision, making it ideal for financial and other precision-required inputs.

min: The minimum value allowed. max: The maximum value allowed. decimalLength: Maximum number of decimal digits. replaceLastIfExceeds: Whether to replace the last digit when exceeding the decimal length (default is true).
