Installation Error : Because boilerplate depends on flutter_localizations any from sdk which depends on intl 0.17.0, intl 0.17.0 is required.

[lakhbawa]

Because boilerplate depends on flutter_localizations any from sdk which depends on intl 0.17.0, intl 0.17.0 is required. So, because boilerplate depends on intl ^0.16.1, version solving failed. pub get failed (1; So, because boilerplate depends on intl ^0.16.1, version solving failed.)

Things I Tried: I changed the int version to .0.17.0 it then created another issue which says f_logs requires int version <0.17.0.

Pls fix asap, I am new to flutter

Hi,

I have updated the DI library for this boilerplate template, please go through feature/null-safety branch for more details. Feel free to reach out to me if you find any issues.

Note: I will merge the changes into master as soon as I am done testing and implementing other features.

Thanks

Sure, Thanks a Lot, I am seeing these errors after updating the code. Pls check

Please go through the readme on how to run this boilerplate project. Thanks

Please go through the readme on how to run this boilerplate project. Thanks

Thanks a lot, it did work.

Just need a little clarification regarding this. Do we have to keep flutter packages pub run build_runner watch running all the time, we code. Or its Just one time process?

Step 3:

This project uses inject library that works with code generation, execute the following command to generate files:

flutter packages pub run build_runner build --delete-conflicting-outputs or watch command in order to keep the source code synced automatically:

flutter packages pub run build_runner watch

[lakhbawa]

Running flutter packages pub run build_runner watch gives following error.

[INFO] Terminating. No further builds will be scheduled

You have hit a bug in build_runner
Please file an issue with reproduction steps at https://github.com/dart-lang/build/issues

Null check operator used on a null value
package:build_runner/src/generate/watch_impl.dart 189:40  WatchImpl.reader

package:build_runner/src/server/server.dart 49:20         createServeHandler.<fn>

pub finished with exit code 1

however flutter packages pub run build_runner build --delete-conflicting-outputs works okay
