Spoiler widget in Flutter

spoiler_widget è un widget per Flutter che ci consente di nascondere un testo, o altro, e visualizzarlo al tap/click.

Prendendo spunto dall'esempio più sotto, giocate con i parametri per capire come nascondere quello che vi serve.

Per installarlo:

flutter pub add spoiler_widget

Qui sotto un esempio:

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

void main() {
  runApp(const MyApp());
}

class MyApp extends StatelessWidget {
  const MyApp({super.key});

  @override
  Widget build(BuildContext context) {
    return MaterialApp(
      title: 'Flutter Demo',
      theme: ThemeData(
        colorScheme: ColorScheme.fromSeed(seedColor: Colors.deepPurple),
        useMaterial3: true,
      ),
      home: const MyHomePage(title: 'Flutter Demo Home Page'),
    );
  }
}

class MyHomePage extends StatefulWidget {
  const MyHomePage({super.key, required this.title});

  final String title;

  @override
  State<MyHomePage> createState() => _MyHomePageState();
}

class _MyHomePageState extends State<MyHomePage> {
  final bool _enable = true;

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      appBar: AppBar(
        backgroundColor: Theme.of(context).colorScheme.inversePrimary,
        title: Text(widget.title),
      ),
      body: Center(
        child: RepaintBoundary(
          child: SpoilerTextWidget(
            particleColor: Colors.black,
            enable: _enable,
            maxParticleSize: 1.5,
            particleDensity: .4,
            speedOfParticles: 0.3,
            fadeRadius: 3,
            fadeAnimation: true,
            enableGesture: true,
            selection: const TextSelection(baseOffset: 0, extentOffset: 15),
            text: 'Testo nascosto! Clicca sulle particelle per visualizzare',
            style: const TextStyle(
              fontSize: 30,
              fontWeight: FontWeight.bold,
              color: Colors.amber,
            ),
          ),
        ),
      ),
    );
  }
}

Enjoy!
