I resolved this issue by doing the following steps:

1. in android/gradle/wrapper/gradle-wrapper.properties change distributionUrl value to distributionUrl=https\://services.gradle.org/distributions/gradle-4.10.1-all.zip.
2. in android/build.gradle change classpath to 'com.android.tools.build:gradle:3.3.0'.
3. *Optional (if using Metro) create metro.config.js in your project directory and put this code into it .
4. *Optional (if using Metro) And make sure version of metro in package.json "metro-react-native-babel-preset": "0.51.0" is right in your packge.json file.
5. remove node_modules folder and run yarn install.

Solution 2:

This happens when you have react native version updated but your project code is not compatible with react native version.

So you need to do changes manually. You can do it by using react-native upgrade helper

https://react-native-community.github.io/upgrade-helper

Specify your current react-native version and the version would you like to update. You can see the changes that need to be done

Resolved my issue by following these steps

1. Remove node_modules and package-lock.json/yarn.lock.
2. Set distributionUrl=https\://services.gradle.org/distributions/gradle-5.4.1-all.zip in gradle-wrapper.properties
3. Add classpath(com.android.tools.build:gradle:3.4.0) in android/build.gradle under buildscript.dependencies.
4. Run yarn.

You may run into other errors due to gradle upgrade which needs to be resolved.
