Latar Belakang

Dalam pengembangan SorBan Naga versi Web, salah satu kendala yang sering muncul adalah gambar eksternal yang gagal dimuat karena masalah CORS (Cross-Origin Resource Sharing). Ini biasanya terjadi ketika gambar di-load langsung dari domain lain (CDN, storage pihak ketiga, dsb.), dan server tujuan tidak mengizinkan akses dari asal domain kita. Masalah ini terutama berdampak pada Flutter Web, yang sangat ketat terhadap aturan CORS saat merender gambar atau file dari server yang berbeda domain.

Solusi: Laravel sebagai Proxy Gambar

Untuk mengatasi hal ini, kita akan membuat proxy sederhana di Laravel, yang bertindak sebagai perantara antara aplikasi Flutter Web dan sumber gambar eksternal. Tujuannya adalah agar gambar diakses seolah-olah berasal dari server kita sendiri, sehingga tidak diblokir oleh kebijakan CORS browser.

Langkah-langkah Implementasi

🛠️ 1. Tambahkan Route Proxy di Laravel (web.php) Buka file routes/web.php di proyek admin panel Laravel kamu, lalu tambahkan route berikut: use IlluminateSupportFacadesHttp; Route::get('/image-proxy', function () { $url = request('url'); if (!$url) { abort(400, 'Missing url parameter'); } $response = Http::withHeaders()->get($url); return response($response->body(), $response->status()) ->header('Content-Type', $response->header('Content-Type')) ->header('Access-Control-Allow-Origin', '*'); }); Penjelasan: - Route ini menerima parameter url dari frontend. - Laravel akan mengambil gambar dari URL tersebut secara backend (server-side). - Gambar dikembalikan ke frontend dengan header yang mengizinkan CORS. 🧩 2. Modifikasi Pemanggilan Gambar di Flutter Web Buka file lib/common/widgets/custom_image.dart, lalu: 🔁 Ganti baris pemanggilan gambar (misalnya baris ke-27) menjadi: '${AppConstants.baseUrl}/image-proxy?url=$image', Ini akan membuat gambar dimuat melalui proxy Laravel, bukan langsung ke CDN. 🔭 Tambahkan import berikut jika belum ada: import 'package:sorbannaga/util/app_constants.dart'; AppConstants.baseUrl harus berisi domain backend Laravel kamu, contoh: https://admin.sorbannaga.com 🗪 3. Build dan Uji Aplikasi Setelah perubahan dilakukan: - Jalankan perintah:flutter build web - Deploy hasil build ke server hosting/web kamu. - Uji di browser: gambar seharusnya kini tampil tanpa error CORS.

📝 Catatan Tambahan

- Pastikan backend Laravel kamu bisa mengakses internet (jika CDN eksternal memerlukan koneksi luar). - Gunakan metode ini hanya untuk gambar atau file publik — proxy ini tidak cocok untuk konten yang membutuhkan autentikasi.

What makes Flutter a Go-to Framework for Developers and Businesses?

In a short time, Flutter has proven its worth and has become a preferred tool for beginner as well as experienced developers.

Not only this, it has benefited several businesses to build strong brand visibility. Here are some core features that make Flutter unique.

Hot Reload: A Game-Changing Feature

It is the key feature of Flutter. It lets developers see changes to their code right away without restarting the app.

This speeds up development and makes it easier to experiment and fix problems.

It boosts productivity and provides a smooth development experience.

Consistent and Beautiful UI Across Platforms

Flutter has many customizable widgets. All you need is to find the relevant one, drag-drop it, and voila.

These help developers make good-looking and consistent apps for different devices. It follows Material Design for Android and Cupertino for iOS.

This makes the app look and feel native on both types of devices. It simplifies design and helps users navigate the app easily, no matter what device they use.

Performance That Matters

Performance is key in app development, and Flutter excels here. It compiles directly to native ARM code, so it doesn’t need a JavaScript bridge.

This means apps start faster and animations run more smoothly. Developers praise Flutter for its speed, making it a top choice for demanding apps like games or video streaming.

A Thriving Ecosystem

A strong developer community is key to a framework's success. Flutter has a quickly growing community that helps improve it.

It is the second most popular open-source project from Google, with over 159,000 stars on GitHub.

Flutter offers many packages, plugins, and libraries to add extra features.

The community helps keep these resources updated and available.

Developers can easily find tutorials and solutions to common problems. This encourages teamwork and the sharing of knowledge.
