Compatibility

| Plugin Version | Capacitor Version | Status |
| -------------- | ----------------- | -------------- |
| 8.x.x | >=8.x.x | Active support |
| 7.x.x | 7.x.x | Deprecated |

Installation

``bash
npm install @capacitor-firebase/crashlytics
npx cap sync
`

Add Firebase to your project if you haven't already (Android / iOS).

#### Crashlytics Gradle plugin

First, add the dependency for the Crashlytics Gradle plugin to your root-level (project-level) Gradle file (/build.gradle):

`diff
buildscript {
dependencies {
+ // Add the dependency for the Crashlytics Gradle plugin
+ classpath 'com.google.firebase:firebase-crashlytics-gradle:2.9.9'
}
}
`

Add the Crashlytics Gradle plugin to your module (app-level) Gradle file (usually //build.gradle):

`gradle
apply plugin: 'com.google.firebase.crashlytics'
`

#### Variables

If needed, you can define the following project variable in your app’s variables.gradle file to change the default version of the dependency:

- $firebaseCrashlyticsVersion version of com.google.firebase:firebase-crashlytics (default: 20.0.3)

This can be useful if you encounter dependency conflicts with other plugins in your project.

To generate human readable crash reports, Crashlytics needs your project's debug symbol (dSYM) files.
The following steps describe how to automatically upload dSYM files to Firebase whenever you build your app:

1. Open your project's Xcode workspace, then select its project file in the left navigator.
2. From the TARGETS list, select your main build target.
3. Click the Build Settings tab, then complete the following steps so that Xcode produces dSYMs for your builds.
1. Click All, then search for debug information format.
2. Set Debug Information Format to DWARF with dSYM File for all your build types.
4. Click the Build Phases tab and complete the following steps:
1. Click the + button, then select New Run Script Phase.

Make sure this new Run Script phase is your project's last build phase; otherwise, Crashlytics can't properly process dSYMs.
2. Expand the new Run Script section.
3. In the script field (located under the Shell label), add the run script based on your package manager:

CocoaPods:
`
"${PODS_ROOT}/FirebaseCrashlytics/run"
`

Swift Package Manager:
`
"${BUILD_DIR%/Build/*}/SourcePackages/checkouts/firebase-ios-sdk/Crashlytics/run"
`

4. In the Input Files section, add the paths for the locations of the following files based on your package manager:

CocoaPods:
`
${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${TARGET_NAME}
`
`
$(SRCROOT)/$(BUILT_PRODUCTS_DIR)/$(INFOPLIST_PATH)
`

Swift Package Manager:
`
${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}
`
`
${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${PRODUCT_NAME}
`
`
${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Info.plist
`
`
$(TARGET_BUILD_DIR)/$(UNLOCALIZED_RESOURCES_FOLDER_PATH)/GoogleService-Info.plist
`
`
$(TARGET_BUILD_DIR)/$(EXECUTABLE_PATH)
`

If you have ENABLE_USER_SCRIPT_SANDBOXING=YES and ENABLE_DEBUG_DYLIB=YES in your project build settings, also include:
`
${DWARF_DSYM_FOLDER_PATH}/${DWARF_DSYM_FILE_NAME}/Contents/Resources/DWARF/${PRODUCT_NAME}.debug.dylib
`

message: 'This is a non-fatal message.',
});
};

import * as StackTrace from 'stacktrace-js';
const recordExceptionWithStacktrace = async (error: Error) => {
const stacktrace = await StackTrace.fromError(error);
await FirebaseCrashlytics.recordException({

Test your implementation

Here you can find more information on how to test the Firebase Crashlytics implementation.
Among other things, you will find information on how to correctly adjust the project's debug settings under iOS and how to test it out.

If you get obfuscated crash reports for iOS, make sure you have initialized Crashlytics correctly and take a look at this guide, which provides some ways to troubleshoot if Crashlytics can't find your app's dSYM.
