For Flutter 1.17 and below kindly stick to v3.12.*

v3.13.0 works for the newly released Flutter 1.20

Thank you for the clarifications! I did try to downgrade to my previous version (3.9) and also did try to use the version 3.12, but when compiling, Flutter stick to the version 3.13... What do I need to do to get it back to a previous version?

[CodeDok]

Changing the version from 3.13.0 to 3.12.2 in the pubspec.lock file and then executing flutter clean -> flutter pub cache repair fixed it for me.

Thank you very much! I will try.

[CodeDok]

No problem. But after fixing the wrong version you'll get another error. Now with the flutter_chips_input plugin which the form_builder depends on. There I couldn't downgrade to an older version. The pubspec.lock file is always updated to the 1.9.0 unfortunately. Whether it is because of the 3.13.0 package which remains in the packages cache is unknown to me.

Only upgrading Flutter to 1.20 fixed it for me.

[ioridev]

I have the same issue.
Is there a way to solve it without upgrading Flutter to 1.20?

Use v3.12.* for Flutter pre-1.20

[danvick]

If this issue persists (ie flutter clean -> flutter pub cache repair doesn't work) and you need to use a lower version of Flutter, then consider using dependency overrides:

dependency_overrides:
  flutter_chips_input: ^1.8.3

Use v3.12.* for Flutter pre-1.20

If you do v3.12, you will get this error.

Because flutter_form_builder 3.1.2 depends on intl ^0.15.8 and every version of flutter_localizations from sdk depends on intl 0.16.1, flutter_form_builder 3.1.2 is incompatible with flutter_localizations from sdk.

[danvick]

Use v3.12.3 (three point twelve) and not 3.1.2 (three point one point two)

[ioridev]

That was a small mistake. Thank you very much!

[christianarduino]

I have the exact same problem. I have Flutter v1.17. I tried to change the package version to 3.12.3, did flutter clean and flutter pub cache repair, but the problem persists. Any solution?

I am using FormBuilder 3.13.5 with Flutter 1.20.4 on stable channel.

[sanjaysingh1990]

@pulstar please try following I had the same issue after many try.

flutter version : 1.20.4
flutter_form_builder: ^3.13.0

[jamilgha]

@pulstar please try following I had the same issue after many try.

flutter version : 1.20.4
flutter_form_builder: ^3.13.0
add this package in dart file in form_builder_checkbox.dart
import 'package:flutter/rendering.dart';

[deandreamatias]

This still a issue?

[pulstar]

This still a issue?

It is fine now.
