A geo-tagged video sharing app with flutter
Spot
Spot is a geo-tagged video sharing app, meaning every video recorded in Spot is saved on a location. Anybody can scroll though the map and find the videos recorded in any location in the world.
DISCOVER With Spot, you can view what is going on anywhere in the world. All videos in Spot are geo-tagged, meaning they are marked at the location they were recorded. That means if you want to take a look at what is going on in New York right now, you just go to NewYork within the app and view what people are posting. Same for LA, Paris, Tokyo or anywhere else in the world!
CREATE You can record Spot videos to let your everyone else know what is happening wherever you are. With our intuitive video recorder, you will be able to capture the moment easily.
ENJOY How you utilise Spot is up to you! You may be able to check out the local festival without actual going there, discover hidden local amazing restaurants, or virtually visit your favorite city in the world. When you visit amazing places, don't forget to save that memory inside Spot so that the world can know about that place!

Getting Started ?
This project contains 3 flavors:
- development
- staging
- production
To run the desired flavor either use the launch configuration in VSCode/Android Studio or use the following commands:
# Development
$ flutter run --flavor development --target lib/main_development.dart --dart-define=SUPABASE_URL=[Supabase Url] --dart-define=SUPABASE_ANNON_KEY=[Supabase annon key]
# Staging
$ flutter run --flavor staging --target lib/main_staging.dart
# Production
$ flutter run --flavor production --target lib/main_production.dart --dart-define=SUPABASE_URL=[Supabase Url] --dart-define=SUPABASE_ANNON_KEY=[Supabase annon key]
*Spot works on iOS and Android.
Running Tests ?
To run all unit and widget tests use the following command:
$ flutter test --coverage --test-randomize-ordering-seed random
To view the generated coverage report you can use lcov.
# Generate Coverage Report
$ genhtml coverage/lcov.info -o coverage/
# Open Coverage Report
$ open coverage/index.html
Working with Translations ?
This project relies on [flutter_localizations][flutter_localizations_link] and follows the [official internationalization guide for Flutter][internationalization_link].
Adding Strings
- To add a new localizable string, open the
app_en.arbfile atlib/l10n/arb/app_en.arb.
{
"@@locale": "en",
"counterAppBarTitle": "Counter",
"@counterAppBarTitle": {
"description": "Text shown in the AppBar of the Counter Page"
}
}
- Then add a new key/value and description
{
"@@locale": "en",
"counterAppBarTitle": "Counter",
"@counterAppBarTitle": {
"description": "Text shown in the AppBar of the Counter Page"
},
"helloWorld": "Hello World",
"@helloWorld": {
"description": "Hello World Text"
}
}
- Use the new string
import 'package:spot/l10n/l10n.dart';
@override
Widget build(BuildContext context) {
final l10n = context.l10n;
return Text(l10n.helloWorld);
}
Adding Supported Locales
Update the CFBundleLocalizations array in the Info.plist at ios/Runner/Info.plist to include the new locale.
...
<key>CFBundleLocalizations</key>
<array>
<string>en</string>
<string>es</string>
</array>
...
Adding Translations
- For each supported locale, add a new ARB file in
lib/l10n/arb.
├── l10n
│ ├── arb
│ │ ├── app_en.arb
│ │ └── app_es.arb
- Add the translated strings to each
.arbfile:
app_en.arb
{
"@@locale": "en",
"counterAppBarTitle": "Counter",
"@counterAppBarTitle": {
"description": "Text shown in the AppBar of the Counter Page"
}
}
app_es.arb
{
"@@locale": "es",
"counterAppBarTitle": "Contador",
"@counterAppBarTitle": {
"description": "Texto mostrado en la AppBar de la página del contador"
}
}
