A problem occurred configuring project ':fluttertoast'.

   > Could not resolve org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0.
     Required by:
         project :fluttertoast
      > The consumer was configured to find a runtime of a component compatible with Java 11, packaged as a jar, and its dependencies declared externally. However we cannot choose between the following variants of org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0:
          - gradle70JavadocElements
          - gradle70RuntimeElements
          - gradle70SourcesElements
          - javadocElements
          - runtimeElements
          - sourcesElements
        All of them match the consumer attributes:
          - Variant 'gradle70JavadocElements' capability org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0 declares a runtime of a component, and its dependencies declared externally:

                  - Provides javadocs but the consumer didn't ask for it
                  - Doesn't say anything about its target Java version (required compatibility with Java 11)
                  - Doesn't say anything about its elements (required them packaged as a jar)
                  - Provides attribute 'org.gradle.plugin.api-version' with value '7.0' but the consumer didn't ask for it
                  - Provides release status but the consumer didn't ask for it
          - Variant 'gradle70RuntimeElements' capability org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0 declares a runtime of a component compatible with Java 8, packaged as a jar, and its dependencies declared externally:
              - Unmatched attributes:

          - Variant 'runtimeElements' capability org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0 declares a runtime of a component compatible with Java 8, packaged as a jar, and its dependencies declared externally:
              - Unmatched attributes:

                  - Provides attribute 'org.jetbrains.kotlin.platform.type' with value 'jvm' but the consumer didn't ask for it
          - Variant 'sourcesElements' capability org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0 declares a runtime of a component, and its dependencies declared externally:
              - Unmatched attributes:
                  - Provides documentation but the consumer didn't ask for it
                  - Provides sources but the consumer didn't ask for it

        The following variants were also considered but didn't match the requested attributes:
          - Variant 'apiElements' capability org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0 declares a component compatible with Java 8, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component and the consumer needed a runtime of a component
          - Variant 'gradle70ApiElements' capability org.jetbrains.kotlin:kotlin-gradle-plugin:1.7.0 declares a component compatible with Java 8, packaged as a jar, and its dependencies declared externally:
              - Incompatible because this component declares an API of a component and the consumer needed a runtime of a component
