Flutter comes with so many facilities and one of them is Analyzing the application source code for errors. Flutter gives us a command named as flutter analyze which is used to Analyze Flutter Dart Code for Errors. The Analyze command would start analyzing the dart code from beginning and goto end of code. If there is any type of Syntax error or code implementation error like keyword mistake, initialization mistake and declaration mistake then Flutter analyze command will find all the errors and print them on the Command Prompt or Terminal screen. Using this technique we can remove errors from our flutter code without executing in real device or emulators.
Contents in this project Find Analyze Flutter Dart Code for Errors and Remove Errors Line by Line Android iOS Example:
1. To analyze flutter dart project code for errors first we have to open the Flutter project root folder in Command Prompt or Terminal like i did in below screenshot.
3. Now i will remove a Comma between two widgets and make a Error and again execute the flutter analyze command.
Now in above screenshot you can see it will find the Error and print the error solution on Terminal screen with Line to line solution. This is how the Analyze command will works in flutter.
4. The flutter analyze command also has a sub command known as flutter analyze –watch which is used to continuously monitor the file changes and print error message on screen. All we have to do is run the above command on terminal screen and start editing or modifying the source code. If somehow we write the wrong syntax code then it will display us a error message on Terminal screen.
