I have already tried flutter upgrade and already reinstalled the flutter but could not able to resolve it. Could you please help me with this?
Thanks in advance

I'm not really an expert in iOS builds. Are you on the beta channel (flutter doctor)? Did it work without the plugin? did it work with another plugin (such as shared_preferences). You might have to run pod install from the ios folder too. Make also sure you upgrade to the latest version (flutter and sqflite).

@alextekartik , Thanks for the prompt reply. And yes, It worked fine without installing plugin. Moreover, as soon as I added this plugin and removed it, my normal projects also stops working. Here is the result of flutter doctor command. Below is the output.

I have also tried with pod install command. Still receiving the same error. And I am in beta branch. Below is the flutter version command output.

flutter doctor seems to show a warning on your iOS setup. Can you try to update XCode to 9.4.1 (it seems that you have only 9.3 installed)?

[vyasdarshan]

@alextekartik, Yes sure. will update it and let you know the result.

@Rassell Sorry for the troubles you getting into

You mean you have the same issue your build system not finding 'Flutter.h' during the build?
I added a section regarding iOS here: https://github.com/tekartik/sqflite/blob/master/doc/troubleshooting.md#ios-build-issue

I don't test much with the master channel (i use mostly beta). I just tried the example app and it works fine for me. Can you try the following?

# Switch to master
flutter channel master
flutter upgrade

# Get the project and build/run the example
git clone https://github.com/tekartik/sqflite.git
cd sqflite/example

flutter packages get
# build for iOS
flutter build ios
# run!
flutter run

My flutter doctor ouput is about the same as yours. Can you confirm that you can easily integrate an officiel simple plugin such as path_provider and that the sqlite example app does not work on your side?

If other iOS users already encountered such issue and have a solution, your input is welcome! @GameXStudio do you still have the issue?

[Rassell]

I just got an strange issue:

Follow the steps, worked fine (not the build because of the signature) but yes the "run", moved to my project, run correctly, tried to build, get the same error again, also trying to run the example code after:

Launching lib/main.dart on iPhone 8 in debug mode...

Damn it. It seems that other users have similar issues on other plugins:

• "Flutter/Flutter.h not found." on iOS. flutter/flutter#16036
• Podfile: update to new version spritewidget/spaceblast#3
• Error building for iOS bluefireteam/audioplayers#48
• Error with video_player plugin on iOS flutter/flutter#21592
• CocoaPods 1.5.3 doesn't support ImagePicker! flutter/flutter#17899

Some suggestion are to remove the Podfile.lock, update CocoaPods, updating the Podfile, building again...Maybe you can try the suggestions. If one of them work, let me know. Can you also confirm that if you try the example in shared_preferences (https://github.com/flutter/plugins/tree/master/packages/shared_preferences) it works? (i.e. to know if you have this issue with any plugin of just sqflite)

[vyasdarshan]

@alextekartik , I have resolved this issue. It was my silly mistake. I have saved the flutter sdk in a folder named "DEVELOPMENT" which is in capital letters and in flutter it was searching the file in the smalll lettered "development" folder.

[Rassell]

Damn it. It seems that other users have similar issues on other plugins:

* [flutter/flutter#16036](https://github.com/flutter/flutter/issues/16036)

(i.e. to know if you have this issue with any plugin of just sqflite)

Yes with 'shared_preferences' worked fine, was moving to 'shared_preferences' to sqflite when i found this issue.

Also tried a lot of suggestions, no one of them worked

[Rassell]

It seems that is a issue related to flutter sdk, on another pc I have 0.11.9 instead of 0.11.13 and working like a charm... :/

[alextekartik]

Ok good to know. Being on the master channel has some risk. Unless you have the needs, you should be on the beta channel which is more stable.
