আপনার অ্যাপের মধ্যে লগইন ফ্লো, উইজার্ড বা অন্যান্য সাবফ্লোগুলি সাধারণত নেস্টেড নেভিগেশন গ্রাফ হিসাবে সবচেয়ে ভালোভাবে উপস্থাপন করা হয়। এইভাবে স্ব-অন্তর্ভুক্ত সাবনেভিগেশন প্রবাহকে নেস্ট করার মাধ্যমে, আপনার অ্যাপের UI এর প্রধান প্রবাহ বোঝা এবং পরিচালনা করা সহজ।
উপরন্তু, নেস্টেড গ্রাফগুলি পুনরায় ব্যবহারযোগ্য। তারা একটি স্তরের এনক্যাপসুলেশনও প্রদান করে- নেস্টেড গ্রাফের বাইরের গন্তব্যগুলির নেস্টেড গ্রাফের মধ্যে থাকা কোনো গন্তব্যে সরাসরি অ্যাক্সেস নেই। পরিবর্তে, তাদের navigate() নেস্টেড গ্রাফে, যেখানে অভ্যন্তরীণ যুক্তি গ্রাফের বাকি অংশকে প্রভাবিত না করেই পরিবর্তন করতে পারে।
উদাহরণ
আপনার অ্যাপের শীর্ষ-স্তরের নেভিগেশন গ্রাফটি অ্যাপটি চালু করার সময় ব্যবহারকারী যে প্রাথমিক গন্তব্যটি দেখেন তার সাথে শুরু হওয়া উচিত এবং আপনার অ্যাপটি নিয়ে যাওয়ার সময় তারা যে গন্তব্যগুলি দেখেন তা অন্তর্ভুক্ত করা উচিত।
উদাহরণ হিসাবে চিত্র 1 থেকে শীর্ষ-স্তরের নেভিগেশন গ্রাফ ব্যবহার করে, ধরুন আপনি ব্যবহারকারীকে শিরোনাম_স্ক্রিন দেখতে চান এবং অ্যাপটি প্রথমবার চালু হলেই স্ক্রিন নিবন্ধন করতে চান। তারপরে, ব্যবহারকারীর তথ্য সংরক্ষণ করা হয়, এবং অ্যাপের পরবর্তী লঞ্চে, আপনাকে সরাসরি ম্যাচ স্ক্রিনে নিয়ে যেতে হবে।
একটি সর্বোত্তম অনুশীলন হিসাবে, শীর্ষ-স্তরের নেভিগেশন গ্রাফের শুরুর গন্তব্য হিসাবে ম্যাচ স্ক্রীন সেট করুন এবং শিরোনামটি সরান এবং স্ক্রীনগুলিকে নেস্টেড গ্রাফে রেজিস্টার করুন, যেমন চিত্র 1 এ দেখানো হয়েছে:
ম্যাচ স্ক্রিন চালু হলে, একটি নিবন্ধিত ব্যবহারকারী আছে কিনা তা পরীক্ষা করে দেখুন। ব্যবহারকারী নিবন্ধিত না থাকলে, ব্যবহারকারীকে নিবন্ধন স্ক্রিনে নেভিগেট করুন।
শর্তসাপেক্ষ নেভিগেশন পরিস্থিতি সম্পর্কে আরও তথ্যের জন্য, শর্তসাপেক্ষ নেভিগেশন দেখুন।
রচনা করুন
কম্পোজ ব্যবহার করে নেস্টেড নেভিগেশন গ্রাফ তৈরি করতে, NavGraphBuilder.navigation() ফাংশন ব্যবহার করুন। একটি গ্রাফে গন্তব্য যোগ করার সময় আপনি NavGraphBuilder.composable() এবং NavGraphBuilder.dialog() ফাংশনের মতো navigation() ব্যবহার করেন।
প্রাথমিক পার্থক্য হল যে navigation একটি নতুন গন্তব্যের পরিবর্তে একটি নেস্টেড গ্রাফ তৈরি করে। তারপরে নেস্টেড গ্রাফে গন্তব্য যোগ করতে navigation() এর lambda-এর মধ্যে composable() এবং dialog() কল করুন।
নিম্নোক্ত স্নিপেট কম্পোজ ব্যবহার করে চিত্র 2-এ গ্রাফটি কীভাবে প্রয়োগ করে তা বিবেচনা করুন:
// Routes
@Serializable object Title
@Serializable object Register
// Route for nested graph
@Serializable object Game
// Routes inside nested graph
@Serializable object Match
@Serializable object InGame
@Serializable object ResultsWinner
@Serializable object GameOver
