FlutterFlow enables powerful app development with drag-and-drop tools and state management — no custom code required. In this guide, you’ll learn how to build a Voice Recorder feature from scratch, with recording, playback, and saved voice notes.

You’ll create:

• A mic permission flow
• A record button
• A list of audio recordings
• Playback functionality using FlutterFlow’s built-in widgets

Let’s walk through the full setup!

Step 1: Create the Data Schema

First, define a local Data Type to store each audio note.

Data Type Name: voiceNoteDS

Fields:

• audioPath (String): the file path of the recording
• createdAt (DateTime): the date and time when it was recorded

This structure will be used to store and display each recording in a list.

Step 2: Create App State Variable

Next, set up a persistent App State variable to hold all voice notes:

App State Variable

• Name: voiceNotesAS
• Type: List<Data (voiceNoteDS)>
• Persistence: ✅ Enabled

This variable will update every time a recording is saved, keeping the list even when the app is closed and reopened.

Step 3: Add Microphone Permission

Before recording, we must ask the user for microphone access.

How to do it:

1. Open the Action Flow for your record button.
2. Add the Request Permission action.
3. Choose Permission Type: microphone

This ensures the app can access the mic before recording begins.

Step 4: Setup Voice Recording Logic (Visual Flow)

Refer to your flow (see screenshot Step 5). You’ll use a conditional to toggle recording on and off.

Logic Flow:

• Condition: isRecording == false
• ✅ TRUE → Start Recording → Set isRecording = true
• ❌ FALSE → Stop Recording → Set isRecording = false → Save file path → Create new voiceNoteDS item → Add to voiceNotesAS

You’ll use the following actions:

• Start Audio Recording
• Stop Audio Recording
• Update Page/App State
• Append to List (voiceNotesAS)

Step 5: Design the UI

Here’s how the layout is structured:

🔹 Main Layout

• Stack for overlapping mic button at bottom
• Column to hold title and recordings list
• ListView for displaying each recorded item

🎵 Inside ListView:

Each item includes:

• The recording timestamp (using createdAt)
• A Play button using Audio Player widget, with audioPath as the file input

 UI Preview

Here’s a screenshot of the working UI:

You can see:

• The page title “Voice Recorder”
• A card-style list of saved recordings with play buttons
• A floating red microphone button to toggle recording

🎯 The clean layout is perfect for voice notes, chat messages, or interviews.

Final Result

When you’re done:

• Tap the mic button to start/stop recording.
• Recordings are saved locally with timestamps.
• They appear in a scrollable ListView.
• Each item includes a play button to listen to the audio.

And all of this is built inside FlutterFlow using built-in widgets, actions, and state — no Dart code needed!

Wrap-Up

You’ve successfully created a fully functional Voice Recorder app in FlutterFlow with:

• Mic permission handling
• Dynamic UI
• Persistent storage
• Instant playback

This feature can now be reused in note-taking apps, audio journals, or messaging apps.

Let me know if you’d like this exported as PDF, Markdown, or submitted to the FlutterFlow Marketplace as a reusable component!

Conclusion

In this tutorial, you’ve learned how to create a complete Voice Recorder in FlutterFlow — without writing any custom code. From setting up the data structure and managing app state, to designing a clean UI and handling microphone permissions, each step was accomplished using FlutterFlow’s built-in tools and visual logic.

This voice recorder feature is not only practical but also reusable across various app use cases like:

• Personal voice memos
• Chat voice messages
• Task reminders
• Audio logs

By combining widgets like Audio Recorder, Audio Player, and ListView, along with state management, you’ve built a real-world feature that enhances user experience and app functionality.

Now that your voice recording component is ready, you can extend it even further — perhaps by uploading audio to Firebase Storage, syncing with user accounts, or transcribing notes using AI tools.
