# PowerSync + Supabase + Drift Flutter Demo: Todo List App
2+
3+
Demo app demonstrating use of the PowerSync SDK for Flutter together with Supabase. For a step-by-step guide, see [here](https://docs.powersync.com/integration-guides/supabase).
4+
5+
# Running the app
6+
7+
Ensure you have [melos](https://melos.invertase.dev/~melos-latest/getting-started) installed.
8+
9+
1. `cd demos/supabase-todolist-drift`
10+
2. `melos prepare`
11+
3. `cp lib/app_config_template.dart lib/app_config.dart`
12+
4. Insert your Supabase and PowerSync project credentials into `lib/app_config.dart` (See instructions below)
13+
5. `flutter run`
14+
15+
# Set up Supabase Project
16+
17+
Create a new Supabase project, and paste an run the contents of [database.sql](./database.sql) in the Supabase SQL editor.
18+
19+
It does the following:
20+
21+
1. Create `lists` and `todos` tables.
22+
2. Create a publication called `powersync` for `lists` and `todos`.
23+
3. Enable row level security, allowing users to only view and edit their own data.
24+
4. Create a trigger to populate some sample data when an user registers.
25+
26+
# Set up PowerSync Instance
27+
28+
Create a new PowerSync instance, connecting to the database of the Supabase project.
29+
30+
Then deploy the following sync rules:
31+
32+
```yaml
33+
bucket_definitions:
34+
user_lists:
35+
# Separate bucket per todo list
36+
parameters: select id as list_id from lists where owner_id = token_parameters.user_id
37+
data:
38+
- select * from lists where id = bucket.list_id
39+
- select * from todos where list_id = bucket.list_id
40+
```
41+
42+
# Configure the app
43+
44+
Insert the credentials of your new Supabase and PowerSync projects into `lib/app_config.dart`
45+
46+
# Drift
47+
48+
The `database.g.dart` file containing the \_$AppDatabase class has to be generated if there are changes made to the `database.dart` file.
49+
50+
- `dart run build_runner build` generates all the required code once.
51+
- `dart run build_runner build --delete-conflicting-outputs` deletes previously generated files and generates the required code once.
52+
- `dart run build_runner watch` watches for changes in your sources and generates code with incremental rebuilds. This is better for development.
