How to Resolve SDK or NDK Issue in Flutter (2025) | Hindi Guide

noreply@blogger.com (Unknown) — Tue, 13 May 2025 20:10:00 +0500

Have you run into this frustrating Flutter error?

NDK at 'C:/.../ndk/23.1.7779620' did not have a source.properties file.

Or maybe after updating Flutter or Android Studio, your build just won't work?

Don’t worry — this is a common issue many developers face. In this blog post, I’ll explain why this happens and show you the step-by-step fix in simple terms, with Hindi-friendly explanation.

🤔 What is NDK?

NDK stands for Native Development Kit. It’s a toolset that lets your Flutter or Android project run native C/C++ code, which is sometimes used by plugins like camera, Firebase, or certain animations.

❌ Why Does This Error Happen?

You might see this error after:

Updating Flutter
Updating Android Studio or SDK
Changing or reinstalling the NDK

The root cause is usually:

An incomplete or corrupted NDK folder
The source.properties file is missing from the NDK director

✅ Step-by-Step Solution to Fix the Error

Solution 1

Delete NDK Version Folder and Rebuild

If you're still getting the error even after trying the reinstall method, you can try this quick and effective fix:

✅ Step-by-Step:

Go to your NDK folder location:
(C:\Users\<YourUsername>\AppData\Local\Android\Sdk\ndk)
Inside the ndk folder, you’ll see one or more version folders (e.g., 23.1.7779620, 25.1.8937393, etc.)
Delete the problematic version folder (the one mentioned in the error).
Now open your terminal inside your Flutter project and run:

flutter clean
flutter pub get
flutter run

During the build process, Flutter or Android Studio will attempt to automatically re-download the correct NDK version.

📝 Why This Works:

Sometimes the NDK version folder gets corrupted or partially installed (especially if the internet was interrupted). By deleting the folder, you force Flutter to download it fresh the next time you build your app.

🎥 Watch the Full Tutorial (Hindi)

🎬 Check out the full video walkthrough on YouTube:

Solution 2

🔧 Step 1: Reinstall NDK from Android Studio

Open Android Studio
Go to:
```
Tools > SDK Manager > SDK Tools
```

Uncheck NDK (Side by side) and click Apply
After it’s uninstalled, check it again and click Apply

This will reinstall the NDK properly, including the required source.properties file.

🖐️ Step 2: Verify the NDK Folder

Navigate to this location:

C:\Users\<YourUsername>\AppData\Local\Android\Sdk\ndk

Look for a folder like 23.1.7779620, and check that it contains a file called source.properties.

If it's missing, follow the manual download method below.

💾 Step 3: Manually Download NDK (If Required

Visit the official NDK download page:
👉 https://developer.android.com/ndk/downloads
Download the NDK version mentioned in your error (e.g., 23.1.7779620)
Extract the folder and move it to:

C:\Users\<YourUsername>\AppData\Local\Android\Sdk\ndk\23.1.7779620
Make sure source.properties is present inside the folder.

📝 Step 4: Update local.properties in Your Flutter Project
Go to your Flutter project folder → open the file local.properties → and add this line:
ndk.dir=C:\\Users\\YourUsername\\AppData\\Local\\Android\\Sdk\\ndk\\23.1.7779620
⚠️ Important: Use double backslashes (\) for Windows paths.

🔄 Step 5: Clean & Rebuild the Flutter Project
Open your terminal and run:
flutter clean
flutter pub get
flutter run
This will rebuild your project with the updated NDK setup.
🔒 Optional: Lock NDK Version in Gradle
To avoid this issue in future builds, specify the NDK version in android/build.gradle:

ndkVersion "23.1.7779620"

📌 Summary

This error is caused by a missing or corrupted NDK installation.
The solution is to reinstall or manually add the NDK with the correct source.properties file.
Don’t forget to update your local.properties and Gradle files if needed.
    With these steps, your Flutter project should be back to building smoothly! 🚀
