flutterflow-socket

Automatic Hot Reload of Flutter app after Push to repository at FlutterFlow without any manual source pull and app reload, because every development second matter!

If this project help you reduce time to develop, you can give me a cup of coffee :)

Demo

1. Installation

1. position to your FlutterFlow project in terminal cd /path/to/your/ff/project
2. copy directory ./tools and scripts ./run and ./watch from this repository to your existing FlutterFlow app with this command

curl -sSL https://raw.githubusercontent.com/stepanic/flutterflow-socket/main/installer.sh | sh

3. follow the Setup instructions

2. Setup

1. install entr (for MacOS brew install entr)
2. copy Webhook Proxy URL from installation output or read it from the GITHUB_WEBHOOK_URL variable in ./watch script
3. OPTIONAL: change GITHUB_WEBHOOK_SECRET at ./watch or leave it to default ff-my-github-webhook-secret
4. add a new Webhook at GitHub https://github.com/<ORG_ID|USERNAME>/<REPO_ID>/settings/hooks/new

• Payload URL = Webhook Proxy URL from 2nd step
• Content type = application/json
• Secret = GITHUB_WEBHOOK_SECRET from ./watch

3. Usage

1. get a <DEVICE_ID> with flutter devices
2. run the Flutter app on the device with ./run <DEVICE_ID>
3. open another terminal window/tab and watch for local and remote changes with ./watch
4. make some changes in the FlutterFlow project and click to Push to Repository
5. repeat 4th step multiple times :))

Example

If you want to try how it works before installation at your project then clone this repository https://github.com/stepanic/flutterflow-socket-example and in one terminal execute ./run <DEVICE_ID> and ./watch in another.

How it works

1. Flutter app should be run with --pid-file

• look at https://github.com/stepanic/flutterflow-socket/blob/main/run#L13

2. ./watch script internally is calling ./tools/hotreloader.sh which is sending a signal to Flutter process(es)

• look at https://github.com/stepanic/flutterflow-socket/blob/main/watch#L25-L30
• and https://github.com/stepanic/flutterflow-socket/blob/main/tools/hotreloader.sh
• inspired by https://medium.com/@kikap/how-to-automatically-hot-reload-flutter-when-dart-source-files-change-6e8fdb523004

3. ./watch script internally starts background Node.js process ./tools/github/listen which is listening for new GitHub commits from Webhook via smee.io channel

• look at https://github.com/stepanic/flutterflow-socket/blob/main/tools/github/listen#L28-L35

4. ./tools/github/listen Node.js script internally is calling ./tools/sync for automatic pulling the newest commits from flutterflow branch and merge them to the currently active branch

• look at https://github.com/stepanic/flutterflow-socket/blob/main/tools/github/listen#L44-L57

Advanced

When adding widgets in FlutterFlow which is changing dependencies in the pubspac.yaml or there are modification at Firestore schema or app icon is changed then add DEEP to the commit message before pushing to the repository. For more details please check this https://github.com/stepanic/flutterflow-socket/blob/main/tools/sync#L14-L20

• look at https://github.com/stepanic/flutterflow-socket/blob/main/tools/github/listen#L44-L57
