Is it possible to create image from Text in Flutter?

Question

I am working on an app where users can log into the app and can enter text in a text form field. It can also apply different font styles and font families and generate an image from it.

Is it possible to achieve?

Any help would be highly appreciated

try flutter_pixel package, an alternative to brain_fusion. it provides a quicker way to generate images using AI. hope this will help:

import 'dart:typed_data';
import 'package:flutter/material.dart';
import 'package:flutter_pixel/utilities/index.dart';

class ImageScreen extends StatefulWidget {
  final String title;
  const ImageScreen({Key? key, required this.title}) : super(key: key);

  @override
  State<ImageScreen> createState() => _TestState();
}

class _TestState extends State<ImageScreen> {
  bool isTextEmpty = true;
  TextEditingController textController = TextEditingController();

  Future<Uint8List> _generate(String query) async {
    textController.clear();
    setState(() {
      isTextEmpty = true;
    });
    Uint8List image = await imageGenerator(query, ImageSize.medium);
    return image;
  }

  @override
  void dispose() {
    textController.dispose();
    textController.clear();
    super.dispose();
  }

  @override
  Widget build(BuildContext context) {
    final double width = MediaQuery.of(context).size.width;
    Authenticator.setApiToken('your api-key'); // Replace this with your edenai API key (currently has a free plan as of 02/03/2024).

    return Scaffold(
      appBar: AppBar(
        title: Text(widget.title),
      ),
      body: SingleChildScrollView(
        child: SafeArea(
          child: Center(
            child: Column(
              mainAxisAlignment: MainAxisAlignment.center,
              crossAxisAlignment: CrossAxisAlignment.center,
              children: [
                Padding(

                  child: TextField(
                    controller: textController,
                    decoration: const InputDecoration(
                      labelText: 'Enter Text to Generate Image',
                      border: OutlineInputBorder(),
                    ),
                  ),

                            builder: (context, snapshot) {
