myfatoorah_flutter import package fails build

I have added myfatoorah_flutter package version 1.0.7 and in file I have imported the package as import 'package:myfatoorah_flutter/myfatoorah_flutter.dart'; it fails the build and gives the following error
../../../Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/myfatoorah_flutter-1.0.7/lib/myfatoorah_flutter.dart:609:31: Error: The argument type 'bool Function(bool)' can't be assigned to the parameter type 'bool Function(bool, RouteInfo)'.
- 'RouteInfo' is from 'package:back_button_interceptor/src/back_button_interceptor.dart'
('../../../Downloads/flutter/.pub-cache/hosted/pub.dartlang.org/back_button_interceptor-4.3.1/lib/src/back_button_interceptor.dart').
BackButtonInterceptor.add(myInterceptor);
I have tried following solutions and none of them worked:
changed version of myfatoorah_flutter
switched between channels dev/stable
upgraded flutter sdk
settings.gradle removed and added again
when I remove import line, it works fine, help is required so that I can integrate the payment methods
I am also getting the same error as I tried this way and worked for me.
change version of back_button_interceptor to back_button_interceptor: 4.0.2 in myfatoorah_flutter's pubspec.ymal.

Missing Logger in classpath

I try to compile a Scala library in Bazel. This leads to an error:
error: Symbol 'type <none>.slf4j.Logger' is missing from the classpath.
This symbol is required by 'value com.typesafe.scalalogging.slf4j.Logger.underlying'.
Make sure that type Logger is in your classpath and check for conflicting dependencies with `-Ylog-classpath`.
A full rebuild may help if 'Logger.class' was compiled against an incompatible version of <none>.slf4j.
logger.warn("Foo")

"#maven//:joda_time_joda_time",
"#maven//:org_scalaj_scalaj_http_2_11",
],
)
From what I have read this error usually stems from mixing 2.x and 2.y Scala versions. I cannot for the live of me figure out where I would do this, though.
Had to add org.sonarsource.sonarlint.core:sonarlint-slf4j-sonar-log:4.8.0.14729 as a dependency because it wants org.slf4j.Logger.
Had to look at the sourcecode to find this:
import org.slf4j.{ LoggerFactory, Marker, Logger => Underlying }

ModuleParseError: Module parse failed: iconv-lite

My project was working perfectly fine.. But after doing a git push, I'm suddenly getting an error when I run gulp:
{ [Error: ModuleParseError: Module parse failed:
/Users/xyz/project/node_modules/iconv-lite/encodings/tables/gb18030-ranges.json
Line 1: Unexpected token :
You may need an appropriate loader to handle this file type.
| {"uChars":[128,16 ....
Why is this happening? I have uninstalled and reinstalled this module iconv-lite, but it doesn't seem to help.
I received this same exact error. You'll want to install a JSON loader module. I'm using json-loader in this example.
npm install json-loader --save
Then, you need to add this loader to your webpack.config.js
module: {
loaders: [
{ test: /\.json$/, loader: "json-loader"}
]
}
I had this dependency by an indirect dependency on node-fetch and fixed the issue by adding the following to my webpack.config.js:
externals: {
'node-fetch': 'fetch'
}
Deleting the file solved the issue.
