measure_build 0.1.0

A build package for generating code used by the measure_flutter SDK.

measure_build

measure_build scans your Flutter project and generates a map of all widget types that extend from Flutter's base Widget class. This generated map is used by the Measure SDK to capture layout snapshots with proper widget type information.

• Usage
• Configuration

Usage

1. Install

Add measure_build as a dev dependency:

dev_dependencies:
  measure_build: ^0.1.0
  build_runner: ^2.4.0

2. Run the code generator

dart run build_runner build

This generates lib/msr_widgets.g.dart containing a map named widgetFilter.

3. Use in Measure SDK initialization

Import the generated file and pass the map to your Measure configuration:

import 'package:your_app/msr_widgets.g.dart';
import 'package:measure_flutter/measure_flutter.dart';

final config = MeasureConfig(
  widgetFilter: widgetFilter,
);

Configuration

You can customize the builder's behavior in build.yaml:

targets:
  $default:
    builders:
      measure_build|widget_analyzer:
        # Custom output path (default: 'lib/msr_widgets.g.dart')
        output_path: lib/src/msr/msr_widgets.g.dart

        # Directories to scan for widgets (default: ['lib'])
        scan_directories:
          - lib
          - custom_widgets
        
        # Variable name for the generated map (default: 'widgetFilter')
        variable_name: msrWidgetFilter

• output_path — the path where the generated file will be saved. Defaults to ' lib/msr_widgets.g.dart'.
• scan_directories — a list of directories to scan for widgets. Defaults to ['lib'].
• variable_name — the variable name of the generated map. Defaults to 'widgetFilter'.
