Build Flutter app in release mode for iOS

I have Android Studio with Flutter plugin installed.
Flutter SDK is also installed on my Mac through Android Studio and I know path to it.

I want to run my app in release mode on real iOS device. Not only to hide "slow mode" banner that can be done using this code as I know

new MaterialApp(
debugShowCheckedModeBanner: false,
...

but also to check how my app works.

I found this instructions

but still can't build app in release mode.

Each time I try to run flutter command in terminal, I got:

> flutter: command not found

I think that it is because I had installed Flutter SDK from Android Studio and I should update some pathes.
So what are my steps to build flutter app in release mode using Xcode?

**Building steps**

If you have problems using flutter command in terminal because it is not found - read *Configuring steps* below.

**Step 1**

Open terminal, run command

cd /Users/John/myFlutterApp/

Run

flutter build ios

Open Xcode and run .xcworkspace file in iOS folder. It should now work smoothly and Slow mode banner should be gone.

**Configuring steps**

**Step 1**

Locate folder where flutter is installed on your mac. If it was installed using Android Studio. Just open Android Studio create new flutter project and you will see **Flutter SDK path**.
For example let it be /Users/John/flutter/

**Step 2**

open terminal on your Mac and run

cd /Users/John/

As you can see we are now one level up from SDK path

**Step 3**

run

export PATH=`pwd`/flutter/bin:$PATH

If you now run **flutter** in terminal you should see list of available params. So you can run

flutter doctor

To check is everything is fine with installation.
Now flutter command only works for this terminal session. And if you close it and later open it again and run fuller command - you will get error that this command is unknown. So you want to save flutter command to be available even after terminal was closed.

**Step 4**

run

open ~/.bash_profile

you will see text editor where you need to paste

export PATH=/Users/John/flutter/bin:$PATH

save file. If you close terminal now and open it again - you should be able to run flutter command.

You could do it from Android Studio directly as well.

Even after running `flutter build ios`, Xcode always ran the Debug version (slow mode).

To solve this, I had to change the **Build Configuration** of the **Run** schema:

1. Click on **Runner**, and **Edit scheme**

2. Select **Release** for the Build Configuration of the **Run** schema

Hoping this is helpful.

You can **Run** your application in **[Release Mode][1]** easily in your terminal using :

flutter run --release


And it will switch to **Release Mode** .

But if you don't want to run your app , just want to build your apk or ipa ,
**Use :**

flutter build --release

> You can specify to build for ios by using `flutter build ios`

If you want to use only Android Studio to deploy your app in release mode, you can also add the --release flag to your Run/Debug configuration manually.

Follow these 3 steps:

1. Open your Flutter project in Xcode.
2. Top Bar Product > Scheme > Edit Scheme
3. Build Configuration - Select Release


*Note: Release type flutter app is valid for 7 days on iOS devices.*

I just wanted to build the ios .ipa file for the testing purpose without any hustle, follow are the step I took, and hopefully, they will be helpful.

1. In the terminal run this command.

flutter build ios --release --no-codesign

2. After that go to the folder where the output is stored.

> build/ios/iphoneos

3. After that you will have to create a new directory/folder in the iphoneos folder called "Payload".

4. After that move the output file "Runner.app" (name can be different) to the "Payload" folder.

5. Then compress the "Payload" folder and rename to "YouAppName.ipa".
(make sure to change the extension)

And it's done.

> The solution will help you get .ipa file without signing.
