使用方法

初始化PianoConsents

首先，你需要初始化 PianoConsents。确保在初始化其他Piano插件之前进行初始化。

import 'package:piano_consents/piano_consents.dart';

...

class _MyAppState extends State<MyApp> {
  final _pianoConsents = PianoConsents(
    requireConsents: true,
    defaultPurposes: {
      PianoConsentProduct.pa: PianoConsentPurpose.audienceMeasurement
    }
  );

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlugins();
  }

  Future<void> initPlugins() async {
    ...
    await _pianoConsents.init();
    ...
  }
  ...
}

设置consents

你可以通过以下方式设置特定的consents：

await _pianoConsents.set(
  purpose: PianoConsentPurpose.audienceMeasurement,
  mode: PianoConsentMode.essential,
  products: [PianoConsentProduct.pa]);

设置所有consents

你也可以一次性设置所有consents：

await _pianoConsents.setAll(mode: PianoConsentMode.essential);

清除consents

清除所有设置的consents：

await _pianoConsents.clear();

以下是完整的示例代码：

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

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

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

  [@override](/user/override)
  State<MyApp> createState() => _MyAppState();
}

class _MyAppState extends State<MyApp> {
  final _pianoConsents = PianoConsents(
    requireConsents: true,
    defaultPurposes: {
      PianoConsentProduct.pa: PianoConsentPurpose.audienceMeasurement
    }
  );

  [@override](/user/override)
  void initState() {
    super.initState();
    initPlugins();
  }

  Future<void> initPlugins() async {
    await _pianoConsents.init();
  }

  [@override](/user/override)
  Widget build(BuildContext context) {
    return MaterialApp(
      home: Scaffold(
        appBar: AppBar(
          title: const Text('Piano consents'),
        ),
        body: Center(
          child: Column(
            children: [
              FilledButton(
                  onPressed: () async {
                    await _pianoConsents.set(
                        purpose: PianoConsentPurpose.audienceMeasurement,
                        mode: PianoConsentMode.optIn,
                        products: [PianoConsentProduct.pa]);
                  },
                  child: const Text("Set consents")),
              FilledButton(
                  onPressed: () async {
                    await _pianoConsents.setAll(mode: PianoConsentMode.optOut);
                  },
                  child: const Text("Set all consents")),
              FilledButton(
                  onPressed: () async {
                    await _pianoConsents.clear();
                  },
                  child: const Text("Clear consents"))
            ],
          ),
        ),
      ),
    );
