flutter_quick_look #

iOS Quick Look implementation on Flutter.

Usage #

You need to setup your root view controller as UINavigationController. Example :

// AppDelegate.swift

import UIKit
import Flutter

@objc class AppDelegate: FlutterAppDelegate {
  var navigationController: UINavigationController?;    
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    let flutterViewController: FlutterViewController = window?.rootViewController as! FlutterViewController
    GeneratedPluginRegistrant.register(with: self)
    self.navigationController = UINavigationController(rootViewController: flutterViewController);
    self.navigationController?.setNavigationBarHidden(true, animated: false);
    self.window = UIWindow(frame: UIScreen.main.bounds);
    self.window.rootViewController = self.navigationController;

    return super.application(application, didFinishLaunchingWithOptions: launchOptions)

Import package:flutter_quick_look/flutter_quick_look.dart use FlutterQuickLook.openURL(filePath); to launch Quick Look

You will find the complete example in the example directory.
