Installation

This package has been tested in Android and ios, some features works on flutter web

Add stories_editor: 0.1.8 to your pubspec.yaml dependencies and then import it.

import 'package:stories_editor/stories_editor.dart';

Apk release build

This package uses Ffmpeg to render and create the corresponding video/gif, due to that the size of the application is almost three times larger than normal, to avoid this you must use the following command to split each file in its respective "abi".

flutter build apk --split-per-abi

This command results in three APK files:

<app dir>/build/app/outputs/apk/release/app-armeabi-v7a-release.apk

<app dir>/build/app/outputs/apk/release/app-arm64-v8a-release.apk

<app dir>/build/app/outputs/apk/release/app-x86_64-release.apk
