 # dafl_project_flutter
 
+*```dafl_project_flutter``` est le nom de notre projet Flutter.*
+
+## Gestion de Git
+
+* Ceci est un **ordre** !
+
+Faire les commit en ligne de commande car Android Studio déclare des erreurs factices dans des fichiers créés pour les plateformes.
+
+1. Ajout de tous les fichiers modifiés / ou créés dans la staging area (fichers locaux prêts à être commit)
+
+```shell
+git add -A
+```
+
+2. Validation des fichiers destinées à être envoyé sur le repo
+
+```shell
+git commit -m "Message corresponding to modifications done in my commmit"
+```
+
+*Insérer un message entre les doubles quotes après le ```-m```*
+
+3. Envoi des commit
+
+```shell
+git push origin my_branch
+```
+
+*Remplacer ```my_branch``` par la branche sur laquelle on a voulu trailler*
+
 ## Convention de nommage des répertoires
